Low Rattlebox - Crotalaria maritima


Low rattlebox (Crotalaria maritima) is often considered to be a variant of the common rabbitbells (C. rotundifolia), but it is distinctive and considered a separate species by other taxonomists. Its very distinctive foliage leads me to agree with those that keep these two as separate species. Because of the confusion regarding its status, it is difficult to pinpoint its exact range in Florida and elsewhere. It seems to occur sporadically throughout Florida and there are records from 2 counties in extreme southern Alabama adjacent to Florida.
While the flowers of both species are indistinguishable, it has a different growth form and foliage. While rabbitbells has distinctly rounded leaves, the leaves of low rattlebox are linear, Each leaf is about an inch long and opposite on the stems. This perennial ground cover produces multiple stems that range about 12- 18 inches from the main stem.  They reach only about 6 inches above the ground.
The bright yellow flowers are produced at the ends of these stems and tend to open in the afternoon for a day. They are visited by bees. Pollinated flowers produce a rounded "pea" that turns black in color before splitting open to scatter the seeds. These are a favored food of seed-eating birds such as doves and quail. 
Although this species is most-often lumped together with rabbitbells, look for it in well-drained sunny habitats. This specimen was photographed in a sandhill understory in the Ocala National Forest in Polk County.

Spiked Hoarypea - Tephrosis spicata


Spiked hoarypeas (Tephrosia spicata) is a species with somewhat confused attributes as its flower buds are red, its flowers start out white when they first open in the morning and turn bright red by afternoon. Therefore, it is a difficult plant to ID simply from its flowers and/or from wildflower books with photographs that don't show this metamorphosis.
This is a species of open, well-drained habitats throughout the state, except for the Florida Keys. It also is reported from the entire Southeastern Coastal Plain from Louisiana up to Maryland on the East Coast. These photographs were taken in sandhill habitat within Ocala National Forest.
Spiked hoarypea is a perennial ground cover that emerges in the spring and sends its long thin stems in multiple directions across the ground.  Like other hoarypeas, the stems, leaves and even the flowers are covered in soft hairs.  Each of its compound leaves are composed of 5-15 oval leaflets and reach a length of almost 1 inch. 
As stated above, the flowers are white when they first open in the morning and turn bright red by afternoon. Each bloom is open for a day and they generally occur as pairs on the leaf stem.  Like most members of the legume family, the upper petal is broad and partially covers the fused petals of the lower lip. Each bloom at about 1/2 inch long. Blooming can occur from late spring until mid-fall. Bees are especially interested as pollinators, but it also is used as a host plant by the northern cloudywing skipper.  The seeds, like all legumes, are excellent food for birds such as quail and doves.
For the most part, members of this genus are not propagated by members of the Florida Association of Native Plant Nurseries (FANN) and their somewhat diminutive size and less-than-overwhelming floral display make them a group with limited appeal to the general landscaping public. Their usefulness in a wildlife garden, however, should make then more widely offered. This is not one of the hoarypeas that is currently being propagated at Hawthorn Hill.

Florida Sunflower - Helianthus floridanus



The genus Helianthus is aptly named as Helios was the God of the Sun in ancient Greek culture. There are 16 native species of sunflowers in Florida. Many of them are quite similar in appearance and difficult for the novice to distinguish from each other. Florida sunflower (H. floridanus) is one of those in my opinion. This sunflower shares some of the same characteristics as the common narrow-leaved sunflower (H. angustifolius), but has foliage that differs substantially.
Florida sunflower is a wetland perennial, though it can be found in moist habitats as well. It has been vouchered from Northeast Florida, from the Jacksonville area south to Osceola County. It has not been reported from this region west of the central counties. It also occurs in a four-state region north of us - Georgia, Alabama and the Carolinas. There also are records from Louisiana. 
Florida sunflower is a large robust species that may reach 5-6 feet in height by its late-summer blooming season. It has distinctive wide leathery basal leaves that emerge in early spring. Each is about 6-8 inches long and several inches wide. They are deep green in color and glossy in appearance. Multiple branched stems arise from these leaves. Like most sunflowers, it spreads to form colonies that can become extensive over time.
Flowering occurs in late summer and early fall. The showy yellow ray petals surround a disk of yellow disk flowers. The petals are similar to those of narrow-leaved sunflower, but a bit narrower. They attract a wide variety of pollinators.
Florida sunflower grows best in sunny moist habitats. As a landscape plant it needs a lot of room as it spreads by underground rhizomes and its large size tends to overwhelm less-robust species. I have used it quite successfully in central Florida in plantings at the edge of lakes and wetlands, however. This species is only occasionally offered for sale by native plant nurseries affiliated with FANN - the Florida Association of Native Nurseries and it may take some sleuthing to locate plants for sale. I do not intend to add it to the species I offer here at Hawthorn Hill, but I could change my mind if I felt that there was a demand.

Earred Tickseed - Coreopsis auriculata

Flower while the plant was still in the pot
Foliage of the above, planted in my landscape

Native, or not?  Earred tickseed (Coreopsis auriculata) is not listed on the ISBN site, Florida Plant Atlas, maintained by the University of South Florida, but others list it as such. It was recorded in Florida from one site near a powerline pole in extreme north Florida, but subsequent trips to that site in recent years have failed to rediscover it. Chances are it was "managed" by the utility company out of existence. I have chosen to label it as a Florida native that seems to have been extirpated. This species is rather common to our north, however, being recorded throughout the Southeast Coastal Plain from Louisiana to the Virginias. In these areas, it is found most often in moist open habitats.
I was fortunate in locating this species from a native plant nursery in north Florida and the photos above are from this plant. To date, it has prospered and spread in my new landscape - in full sun and in the moistest part of my new wildflower planting here in west-central Florida.
Earred tickseed is a beautiful, but rather diminutive species. As its Latin and common names suggest, the foliage is distinctively "earred". Each leaf is deep green and glossy, about 2 inches in length, and often lobed near the petiole with two smaller lobes off of the main one. Mature plants rarely stand taller than about 6 inches when not in bloom. In my landscape, it is an evergreen perennial. Plants form side stems and, over time, it becomes a clump that can extend over a foot in width.
Blooming occurs over a several week period in late spring. The flowers are large considering the size of the plant. Each deeply yellow flower head is several inches across and is very glossy. As with most composites, the flowers attract a wide diversity of pollinators.
I hope that this species makes it into the native plant trade here in Florida and that the plant I purchased was not just a lucky break. I also hope to collect seed from my plant next spring and make it available from Hawthorn Hill. Stayed tuned if you are interested - or search for it from native plant nurseries in Georgia or Alabama.

Smooth Blue Aster - Symphyotrichum laeve


There are nearly 30 species of Symphyotrichum asters native to Florida. Some are widespread, but a good many are species with extremely limited natural ranges here - species more common north of us and  ones that have snuck over our border in just a few locations. Smooth blue aster (S. laeve) is one of those. It is vouchered only from Jackson County, west of Tallahassee along the Georgia border. It is widespread north of us, however, and occurs in most states east of the Mississippi River. 
As its common name suggests, this species has smooth leaves and stems - without trichomes (hairs) of any kind. It is a perennial that dies back to the ground each winter and emerges early in spring, eventually reaching a mature height of about 3 feet.  The distinctive leaves are sessile to the stem, wrapping around it in a heart-shaped pattern. The leaves are alternate along the stem, about 1/2 inch wide and 2-3 inches long - becoming smaller as they go up the stems.
Many aster flowers are light blue with yellow disk flowers and this is no exception. These are especially attractive however. The photo above does not do them justice and I hope to get better ones as this plant matures. Each composite flower head is about 1/2 - 3/4 inch wide. A great many of them are produced in late summer to fall at the top of each stem.
This is a species of well-drained open habitats. Over the past few years, I have made a concerted effort to add Symphyotrichum asters to my home landscape and to what I can offer at Hawthorn Hill. All are exceptional at attracting pollinators and I find them to be equally attractive to my eye as well.  Historically, very few of these asters has been cultivated by native nurseries affiliated with FANN - the Florida Association of Native Nurseries. Currently, I have about a dozen species here in my landscape at Hawthorn Hill and I was very excited to find this one for sale recently at The Native Nurseries of Tallahassee. It is reportedly being grown at Superior Trees, Inc. in Lee Florida. It is my hope that I will get seed from this plant and that I can offer it as well next year.

New York Ironweed - Vernonia novaboracensis



Every ironweed (Vernonia spp.) in Florida, except Blodgett's (V. blodgettii) could aptly be called "giant" ironweed based on their growth form, but since that common name was given to just one of them, we've had to call the others by other common names. Just be assured that all of them are "giant" in terms off their mature height at flowering.
There are six species of ironweeds considered to be native to Florida, though one (Stemless ironweed, V. acaulis) has been recorded as an extreme outlier (Polk County) from the main population in the mountains of North Carolina and seems a bit suspicious as a Florida native. New York ironweed (V. novaboracensis) is restricted to 10 counties in extreme north Florida. It is much more common to our north, however, and extends up the Eastern Seaboard to New York and Delaware. As mentioned above, this is a tall perennial species that can reach mature heights of more than 6 feet by late summer. Like other members of this species also, it suckers outward from the main stem over time and forms clumps of multiple stems. New York ironweed prefers moist sunny locations and is most often encountered at the upper edges of marshes and other wetlands.
The wide oval leaves are alternate along the stems. They are toothed along the leaf margins and somewhat pubescent, but not as much as in V. gigantea. The two species can be easily distinguished from each other when compared to each other side by side, but it is more difficult otherwise. One significant difference lies in the flowers. While V. gigantea produces a great many flowers atop its stems, New York ironweed produces fewer and they tend to be more deeply purple in color. Flowering occurs in late summer and fall. As with other members of the genus, they are excellent at attracting pollinating insects - especially bees and butterflies.
Despite the widespread propagation and availability of other native ironweeds in Florida, this species is only very rarely offered. I purchased this one from The Native Nurseries of Tallahassee where it was grown from seed collected by one of the nursery owners. I hope that this continues to be offered and I hope to get seed from my plant to make it available next year from Hawthorn Hill. It is reported that it requires cold stratification and that it often has low germination rates. It also is reported that it will tolerate most landscape conditions except for highly droughty soils, once established. If you can, however, give it a bit of extra moisture.

Dixie Ticktrefoil - Desmodium tortuosum




Ticktrefoils (Desmodium spp.) are a weedy bunch that produce loments (seeds produced in a "string") as seen in the third photo from the top. Each seed in these clusters is covered by hairs that stick to clothing and fur, causing the ripe seeds to break away from the cluster and be carried away from the parent plant. Of the 24 species vouchered from Florida, four are considered to be non-natives and of the remaining 20, Dixie ticktrefoil (D. tortuosum) is considered by some to be native and by others as not. This species was first recorded in Florida in Leon County in 1823, but has since been found nearly statewide in disturbed upland sites. It also occurs to our north, in the Southeast, from Texas to North Carolina. I photographed this one near a parking lot/trailhead in Goethe State Forest, Citrus County.
While some ticktrefoils are relatively prostrate, this species becomes rather tall and winnowy. In Florida, it is an annual and it reaches a mature height of about 3-4 feet by early summer. Like all members of the genus, the leaves are compound with three leaflets. They are oval shaped and the petioles are slightly hairy. Each leaflet is oval in shape with the top one decidedly so. They are about 1 inch wide.
Flowering can occur during most months until late fall. The flowers on this species are produced in pairs along the stem. Each is a typical legume flower, with a keeled lower lip and a broad fan-shaped upper petal marked by a noticeable yellow splotch outlined in a deeper pink. They, like all members of the genus, are pollinated mostly by bees that push their way into the center of the flower to reach the pollen and nectar.
Tick trefoils can be considered a nuisance in a wildflower landscape as the seeds stick to everything. They also are beneficial as they serve as the host plant for three species of skippers - long-tailed, Dorantes and silver-spotted. Left alone, in a fallow field, they can be valuable additions to a butterfly/pollinator garden, but I would not recommend them in landscapes that need to be tended.

Wood Germander/Sage - Teucrium canadense


Wood germander/sage (Teucrium canadense) is a very widespread member of the mint family, common throughout Florida and in nearly every state of the U.S. and province of Canada. It prefers the open sunny edges of wetlands and is most often encountered at the upper edges of marshes and wet prairies.
This is a robust perennial that dies back to the ground in winter and often reaches three feet in height by the summer months. The leaves are large - up to 4 inches long and elliptical in shape. They also are opposite along the stem, deep green, with noticeable teeth along the leaf margins.  In a lot of settings where wood germander occurs, it will stand above the other plants in the plant community.
Blooming occurs in summer and fall.  The flowers occur at the top of the stems, and blooming starts at the bottom, working upwards towards the top over several weeks. Like most mints, the flowers have a broad lower lip and two smaller upper petals. These recurve upwards and look like tiny wings. The pale lavender blooms are spotted with deep pink dots.. They are quite attractive to pollinating insects of all kinds.
Although this is an attractive wildflower with excellent value as a pollinator plant, it requires moister soil than most can give it and it suckers very aggressively when planted in the right conditions. For this reason, it is rarely propagated by any of the native plant nurseries in Florida affiliated with FANN - the Florida Association of Native Nurseries. Although it does not play well with others in a typical landscape setting, it would be a very valuable addition to a wetland restoration one. Like other mints, it produces copious amounts of seed by early fall and should be easy to propagate if the tiny seed were scattered on the surface of soil kept moist to wet.

Beach False Foxglove - Agalinis fasciculata


There are 16 species of false foxgloves (Agalinis spp.) vouchered in Florida and most are quite difficult for even seasoned botanists to distinguish from one another. Beach false foxglove (A. fasciculata) is one of the most frequently encountered species, however, occurring statewide in a wide variety of habitats - including beach dunes, throughout the state. It also occurs throughout the eastern half of the U.S. from Texas in the west, to Kansas and Illinois in the Midwest, and to New York in the east.
False foxgloves are annuals and root parasites. As such, they require a nearby and suitable host plant shortly after germination to persist. For this reason, they are not propagated by any of the nurseries I am familiar with. I have had great success in getting seeds to germinate, for example, but no luck getting the seedlings to a size suitable for transplanting into a wildflower bed.
Growth is rapid in the spring. The plants reach their mature height of about three feet by mid-summer. In this species, the leaves are narrow and linear, about 1 inch long and appressed against the stem.
Flowering occurs in the summer to fall. Each light purple flower is about one inch long, with a deep throat speckled with darker purple dots and often with a few yellowish lines. There are five petals fused together to form the floral tube. The blooms are of particular interest to large bees such as bumblebees.
False foxgloves serve as an important host for the common buckeye butterfly.  As such, they would be a valuable addition to a mixed butterfly garden if this species were more easily propagated.  These species all produce numerous seed capsules that ripen in fall and each is filled with a great many tiny dark seeds. For anyone desiring to give this plant a try, scatter the seed on the soil surface in a mixed planting and hope for the best.

Partridge Pea - Chamaecrista fasciculata


The common partridge pea (Chamaecrista fasciculata) is found throughout Florida in a wide variety of open habitats. It also occurs throughout the eastern two-thirds of the U.S.  It prefers well-drained soils, however, and is most often encountered in open fields as well as in sandhills, dry flatwoods, and along beach dunes. It is salt tolerant. 
Plants emerge from the seed bank mostly in early spring and mature rapidly. Unlike its close cousin, sensitive pea (C. nictitans), partridge pea is a rather low-growing species - rarely standing more than two feet tall at maturity.  The leaves and stems are glabrous (without hairs) and the leaflets are not sensitive to touch, though they tend to close up in the evening and reopen the next day. Each leaf is composed of a great many oval leaflets.
Flowering generally occurs in summer and fall. The bright yellow flowers are composed of five unequally sized petals and often have a red mark at their base - as seen in the above photographs.  The flowers are mostly bee pollinated and seem to be especially of interest to bumblebees.  As the common name suggests, the ripened seeds are a favorite food source for ground-feeding birds such as doves and quail.
Partridge pea is a favorite plant among butterfly gardeners as it serves as a larval host plant for at least three species of sulfur butterflies as well the ceraunus blue.  Because of this, it is often propagated by native plant nurseries. As an annual, however, it must be allowed to reseed if it is to persist. This is rarely a problem, however, and most gardeners find that they have to thin the new seedlings out a bit if they are using it in a mixed planting bed.  As flowering occurs over a long number of months, it is usually easy to find some seed along a roadside (never collect in protected areas) and sow them yourself.

Sensitive pea - Chamaecrista nictitans

Partridge peas are annuals that serve as larval hosts for several sulfur butterflies when in bloom. They also serve as the host plant for the gray hairstreak and ceraunus blue. Of the seven species recorded for Florida, four are native and two of these are widespread throughout the state. Sensitive pea (Chamaecrista nictitans) is one of these.  Two varieties have been described based on the presence or absence of hairs along the leaf stems. The one photographed above is C. nictitans var. aspera. 
Sensitive pea occurs in a wide variety of open habitats. As a somewhat "weedy" species, it is most often encountered in disturbed sites, along trails, and at the edge of roadsides, but it also can be seen in flatwoods and dry prairie habitats.  It is recorded throughout much of the eastern U.S. - from Arizona in the west and in all of the Eastern and Midwestern states to the Atlantic.
This is a robust plant and may reach four feet tall at maturity. The stems are somewhat woody in appearance and it produces numerous upright branches. As in other members of the legume family, the leaves are compound. Each is about 2 inches long with a great many narrow leaflets. What separates this from other members of the genus is that they are touch sensitive. The leaflets fold when touched - as can be seen in the above photograph. They also close as evening approaches and open again the next morning - a phenomenon known as a "sleep movement." 
Sensitive pea has smaller yellow flowers than its frequently encountered cousin - partridge pea (C. fasciculata). The blooms also do not fully open in the same way. They are composed of five unequally sized petals. 
Sensitive pea is an important host plant for butterfly gardeners, but is weedy and has a tendency to spread - making it a poor player in small mixed wildflower plantings. Perhaps for that reason, it is very infrequently offered for sale by nurseries affiliated with the Florida Association of Native Nurseries (FANN).  It is easy to grow from seed, however. As it remains in flower for most of the growing season, the small hairy seed pods can also be found in most months. If you wish to grow it from seed, scatter them on the soil surface. You won't need very many to get it established.

Shrubby False Buttonweed - Spermacoce verticillata



Although this blog is devoted to Florida NATIVE plants, I have from time to time posted about a nonnative that is widely seen in natural areas. This is one of them. Woodland false buttonweed (Spermacoce verticillata) occurs throughout peninsular Florida in a wide variety of open habitats. I photographed these at Kissimmee Prairie Preserve State Park in Okeechobee County. It is classified as a Class II invasive plant by the Florida Exotic Pest Plant Council (FLEPPC). Of the eight species vouchered for Florida, six are natives. All are considered "weeds" due to their habit of spreading quickly in disturbed locations.
This species is well-visited by pollinating insects and its numerous flower heads produce large amounts of seed. Most species in this genus are low growing, but shrubby false buttonweed becomes almost woody and reaches a mature height of about 2-3 feet. It is a perennial. The foliage is narrowly elliptical, deep green and shiny. Flowering can occur during nearly every month if temperatures do not go below freezing.
Although it would be a reasonable addition to a pollinator garden, its cultivation should be avoided - especially in areas anywhere near a natural area.

Carolina Goldenrod - Solidago arguta var. caroliniensis

Flowers

Flower Close Up

Stems
Goldenrods (Solidago spp.) are often difficult for the average wildflower enthusiast to identify to species. Their bright golden flowers are dead giveaways to bring you to the genus level, but after that it can get confusing. This could be the case for this one, Carolina goldenrod (S. arguta var. caroliniensis) without a close look at its foliage and the arrangement of its flowers during its summer bloom time.
Lower leaf
Two years ago, I was fortunate to purchase a couple of specimens from Marc Godts at Green Isles Nursery in the Groveland area of central Florida and these photos come from the plants I added to my wildflower garden. This species has been vouchered in most Florida counties in the northern third of the state. This variety also is widespread throughout the states of the Southeast - from Missouri and Louisiana to Maryland south along the Atlantic coast. Other varieties of this species occur as far west as Texas, through much of the Midwest and throughout the Eastern Seaboard, including populations in Quebec. Yet, despite its extensive range, very little seems to have been written about it. It is not mentioned in any of the Florida wildflower books that I own, for example.
It is reported that it occurs mostly in areas of woodland openings, such as outcrops or clearings. In my landscape, it has not been fussy about growing conditions. I have them planted in average, Florida sandy soil in full sun. It is a perennial, like other members of this genus, and dies back to the ground in winter. In spring, it forms a basal rosette of rather large oval leaves that are slightly toothed. These tend to die back, however, as the flower stalks extend in early summer. Eventually, the plants reach about 3 feet in height. The leaves and the stems are slightly "hairy" and the upper leaves along the stems become smaller and more elliptical. The ones in these photographs are about 1 inch in length. Often, the stems are somewhat reddish as well.
Flowering occurs in mid-summer, before most of the other goldenrods bloom in my landscape. A great many open panicles form at the top of the main stem and small heads of about 20 flowers occur along each side stem. This aspect, as shown in these photos above, is diagnostic for any of Florida's native goldenrods that I've encountered - or grown. The flowers are a more-lemon yellow color than most others as well.
Like other members of this genus, the blooms are especially attractive to pollinating insects. It is a wonder to me that more species are not routinely available from native nurseries here in Florida and I feel fortunate that Marc chose to propagate a few that year. Many goldenrods make poor additions to a mixed wildflower garden because they sucker extensively and I have been looking for and propagating/growing as many as I can find in order to"weed out" those aggressive species. So far, Carolina goldenrod has played well with its neighbors in my landscape. It is easy to propagate from seed and I hope to add it to the plants I offer next spring at Hawthorn Hill.

Peninsula Axilflower - Mecardonia acuminata


Peninsula axilflower (Mecardonia acuminata) is a very common wildflower in the understory of moist open habitats throughout Florida. The photos above reflect the subspecies P. acuminata subsp. peninsularis, which is a Florida endemic and found throughout much of central and south Florida. Other subspecies are found in Florida as well. Subspecies M. acuminata subsp. microphylla is a rare form vouchered only from Washington and Calhoun Counties in north Florida while subspecies M. acuminata subsp. acuminata is widespread in north-central and north Florida. The differences lie in the leaf shape and that is reflected in their various subspecies names. The species also is widespread throughout much of the eastern U.S.; its range extending from Texas to the west, north to Illinois, and east to Maryland.
This diminutive ground cover is easily overlooked by the casual hiker. It rarely stands more than 6 inches tall and grows mostly prostrate across the ground.  As such, it sends up multiple stems with dark green elliptical leaves. The subspecies photographed above, has noticeable teeth on the leaf margins. Each is about 1 inch long.  Peninsula axilflower is a perennial.
Flowering occurs from late spring to late fall.  The small tubular white flowers are produced near the tips of each stem and are horizontal to the plane of the ground below. Distinct purple lines are noticeable along the outside of the petals.  The flowers are about 1/2 inch in length.They seem to be of most interest to bees.
Peninsula axilflower, is almost ubiquitous to the edges of wet habitats in Florida, but it has never been propagated, to my knowledge, for wetland restoration projects by any of the native plant nurseries affiliated with FANN - the Florida Association of Native Nurseries. Perhaps it is simply not showy enough or too diminutive to warrant that kind of attention, but I always enjoy seeing it when hiking in its preferred habitats.

Pineland Catchfly - Polanisia tenuifolia



Pineland catchfly (Polanisia tenuifolia) is a common plant of central Florida sandhills and scrub, though it is found also throughout these types of upland habitats in much of north and central peninsular Florida and has been reported in Georgia, Alabama and Mississippi. It is an annual, emerging from the seedbank in early spring and maturing quickly to flowering age by late spring to late summer. 
This is a very slender plant (it's other common name, slender clammyweed, reflects this) that reaches about three feet in height. Very narrow, 3-parted leaves line the stem. They are about 1-2 inches long. The stems branch frequently and the white flowers are produced at the ends of each. Each flower is about 1/2 inch wide. The two upper petals are quite noticeable while the lower three are reduced in size. They seem to be mostly pollinated by bees.
The common name of "catchfly" is due to the fact that small insects can be trapped in the somewhat viscid secretions of the stems and leaves. It is not considered insectivorous, however, in the true sense. The purpose of this trait is not well documented and may be similar to tarflower (Bejaria racemosa) where it seems to protect the plant from small sap-sucking insects that would otherwise damage the flowers.
Pineland catchfly is an interesting species that is easily overlooked when not in bloom, but its growth habitat does not lend itself well to most landscape applications. I have never seen it offered for sale by any of the nurseries affiliated with FANN - the Florida Association of Native Nurseries or by other native nurseries in other states where it occurs. It is simply a plant to admire when hiking during the early summer in well-drained upland habitats.

Fall Open House - New Location in Pasco County

Wildflowers in my new landscape
Black-eyed Susan seedlings
The new nursery in my backyard
Most of you likely know that I moved last October from my former home in Seminole to a rental home in Holiday - just north of Tarpon Springs in south Pasco County. Here, I've been working diligently to set up my new landscape and nursery. Things are coming together rather well so far and I'll be ready to host my first Open House on Sunday October 13 from 9 am - 1 pm. I hope to have about 40 species of seedling wildflowers for sale at this time, as well as a few woody plants. As the date gets a bit closer, I will post a species list.
Mark your calendars if you're interested in seeing my new developing landscape and in purchasing a few hard-to-find wildflowers for your own.

You also can follow the progress of my landscape by following my new blog - werenofences.blogspot.com

 My new address is:

Pineland Croton - Croton linearis

Aspect

Flowers close up

Foliage
Pineland croton (Croton linearis) is a small semi-woody shrub confined in Florida to the most-southern counties along the east coast of the state - from St. Lucie south to Miami-Dade. In this region, it occurs most frequently in pinelands. Pineland croton also occurs in the Bahamas and Greater Antilles.
Mature plants form a somewhat woody stem that can reach six feet tall, though often several feet shorter. The main stem is thin and remains flexible. It becomes a multi-stemmed plant. The leaves are alternate along the stem and decidedly elliptical. Each leaf is one inch long, sometimes as long as two inches. The underside of each leaf is covered by silvery hairs.
Flowering can occur in any month. Like other crotons, the male and female flowers are morphologically different, but on the same plant. The male flowers (the ones mostly pictured above) have longer petals and noticeable sepals below while the female flowers are smaller and without noticeable sepals. These attract small bees for the most part. Pineland croton serves as the host plant for two of South Florida's most unique butterflies - the Florida leafwing and Bartram's hairstreak. As such, it makes a very valuable addition to a butterfly garden within the geographic ranges of these two butterflies.
Pineland croton does not seem to be especially fussy in regards to its growing conditions. Although native to high pH soils. it has done very well in my landscape built on a former acidic pineland soil. It is sporadically offered for sale by native plant nurseries in extreme south Florida, but may be difficult to find without some sleuthing.  Mine came from a friend who propagated a few from plants in his yard. I do not intend to propagate seedlings from this plant in the future at Hawthorn Hill.

Large-flowered Meadow Pink - Sabatia grandiflora

Meadow pinks (Sabatia spp.) are also called rosegentians - the problem with common names. Regardless, they comprise a large genus of native wildflowers native to wet and moist-soil habitats. Large-flowered meadow pink (S. grandiflora) is common throughout Florida at the upper edges of marshes and in moist flatwoods and prairies. It also is found in Georgia.
These are annuals. New seedlings emerge in the early spring and grow rapidly. Blooming occurs by summer and generally lasts well into fall before going to seed. As its names indicate, this species tends to be taller than most other members of this genus and the rich pink petals are often bit larger. They are generally a bit wider than 1 1/2 inches. Many members of this genus are somewhat similar in size and flower color, however, and this makes identification difficult for many in the field. To correctly identify this species, look for the upper leaves. In this species, they are thick, wrinkled and wider than the stem. The flowers are primarily pollinated by bees.
Meadow pinks make a stunning addition to many moist-soil habitats in Florida. It is nearly impossible not to encounter at least one species while in the field from summer through fall, but they are not often propagated because of the annual lifestyle. Seeds are produced in rounded capsules by fall to early winter. These can be scattered in wet meadow restoration projects and, once established, they should reseed and maintain themselves over time.

Cuban Meadowbeauty - Rhexia cubensis



Stem with Decidedly Prickles
Despite its common name Cuban meadowbeauty (Rhexia cubensis) has a rather extended range in Florida. It has been reported from nearly every county in Florida and also occurs from Louisiana to North Carolina region of the Southeastern Coastal Plain. It also occurs in parts of the Caribbean, and as its name suggests, the type specimen was first collected in Cuba.
Meadowbeauties are mostly perennials with flowers in various shades of pinks - sometimes white (there also is a yellow one in north Florida). Their urn-shaped seed capsules are the dead giveaway in getting them to genus. Getting the pink ones to species, however, requires a close look at various details of the stems and buds. Cuban meadowbeauty is often a much deeper shade of pink than the other seven mostly pink species. Each bloom is larger than most too - about 2 inches across. What is most distinctive, however, as the still hairs that occur up the stem, along the leaf margins, and on the urn-shaped ovary below the petals. These hairs are stiff and very noticeable to the touch.
This is a species of moist soils - flatwoods and prairies. It can occur in average moisture soils, but it thrives only in situations where it gets wet during the summer rainy season.
Like other members of this genus, the summer flowers have 4 large petals and an inner center of extended yellow anthers. In Cuban meadowbeauty, these anthers are greatly extended. Meadowbeauties seem of special interest to bumblebees, but other pollinating bees visit them.
This genus, though showy, is rarely propagated by nurseries not specially devoted to wetland restoration. I have found them to be difficult in mixed wildflower settings, though they spread easily in naturalized wildflower meadows that maintain adequate soil moisture. Look for this species throughout the state, but don't rely simply on the color of the petals to distinguish it. Look at (and feel) stem for the bristly hairs.

Bahama Aster - Symphyotrichum bahamense


For some reason, Bahama aster (Symphyotrichum bahamense) gets left out of Florida wildflower books. Admittedly, it is not as showy as most in this diverse genus, but it has a special charm of its own in my opinion. It also is one of the most widespread members of this genus of perennial wildflowers in Florida and, thus, often encountered in the field. It is reported throughout peninsular Florida, from the Big Bend all the way to extreme south Florida. It also has been reported in Georgia and Louisiana, though its range in those two states is restricted. It is classified as an obligate wetland plant - a species that only occurs in wet soil habitats. Therefore, it also is a bit problematic adding it to a "normal" wildflower garden.
Bahama aster is a winnowy species. The narrow basal leaves emerge in spring and a tall thin flower stalk emerges shortly after. The leaves along this stalk are much reduced in size. At maturity, the stalk stands about 3 feet tall. The small white flowers are present by mid-summer. They have a light lavender blush to them and surround a center of yellow disk flowers. Each bloom measures about 1/2-3/4 inch across.  Like all members of the aster family, they are of interest to pollinating insects.
I have never seen Bahama aster offered for sale by any of the nurseries affiliated with FANN - the Florida Association of Native Nurseries and, although I currently propagate a large number of Symphyotrichum asters at Hawthorn Hill, I do not have plans to propagate this one at this time either. That could change if there was a demand for it, but its use seems mostly limited to wetland restoration plantings where pollinators are a special interest. Look for it from summer into early fall in open wet habitats - and along wetland ditches. If you are on the lookout for it, I'm betting you will find it.
