Halberd-leaved Hibiscus - Hibiscus laevis

Halberd-leaved hibiscus (Hibiscus laevis) is yet another perennial native Florida hisbicus species common to wet soils. This one is rather uncommon here; native to only 10 counties in the Florida Panhandle.  It is extremely widespread elsewhere, however, and occurs throughout the eastern two-thirds of the U.S. and in Ontario as well. As would be expected, it dies back to the ground each winter and reemerges in spring.  

Like most of our native hibiscus, halberd-leaved hibiscus eventually attains a mature height of about 6 feet in early summer.  It has a straight stout main stem  and numerous small side branches.  The leaves alternate on the stem and are distinctive in shape - as evidenced by the last photo above.  As the common name signifies, they are halberd-shaped -  a two-handed pole weapon that came to prominent use during the 13th-16th centuries. The halberd consists of a specially shaped axe blade not too different than the blade of these leaves.

The flowers are produced at the axils of the leaves beginning near the top of the stem. Multiple blooms are produced singly or a few at a time during the early to late summer as the plant reaches its final height.  They remain open only for a day.  Flower color can be quite variable; from white (very similar to H. moscheutos) to a deep rosy pink (not unlike H. grandiflorus) but always with a bright crimson-colored center.  The flowers above are between those two extremes. Each flower is about 3 inches across.

Halberd-leaved hibiscus, like other members of this genus, attract the attention of a wide variety of pollinators. Hibiscus as a genus are hosts for several moths, including the Io.  Although many of our native hibiscus are widely propagated and sold by native plant nurseries affiliated with FANN - the Florida Association of Native Nurseries, this species has been ignored to date. Hopefully, this will change and this beautiful species will become more available to native plant gardeners.  I have been growing this now for 2 years at Hawthorn Hill and hope to continue its propagation through the years to come.

Fringed loosestrife - Lysimachia ciliata

Fringed loosestrife (Lysimachia ciliata) is a perennial wildflower native to only Jackson, Gadsden, and Liberty Counties in the central Panhandle region of Florida, but it is common throughout much of the U.S. except California and Nevada in the far Southwest.  Throughout its vast range in our nation, it occurs in seasonally wet soils along stream banks and similar habitats with rich organic soils and in shady to partially sunny areas.

This species dies back to the ground in early winter and reemerges in early spring.  Eventually, it reaches a mature height of nearly 3 feet.  It produces an upright thin stalk that is unbranched or slightly branched. The leaves are simple and lanceolate, and they occur opposite each other.  As its name implies, the leaf stems are covered with simple hairs.  

Flowering occurs in early summer (May, June).  The bright yellow blooms are about 1 inch across and are produced in open clusters atop the main stem.  They are especially attractive to bees.  Pollinated flowers form rounded seed capsules

This showy wildflower would make a nice addition to a moist area in the understory of a deciduous woodland or partly sunny wetland edge.  It has never, to my knowledge, been sold commercially by members of FANN - the Florida Association of Native Nurseries, but it is available by many native nurseries north of us.  How these seeds/plants would fare in Florida is unknown.

Long-leaved Summer Bluet - Houstonia longifolia

 

Long-leaved summer bluet (Houstonia longifolia) is a rather rare herbaceous perennial wildflower vouchered only from Walton, Washington, and Jackson Counties in the central Florida Panhandle, but widespread to our north; occurring in nearly every state in the eastern half of the nation.  Throughout, it is most often found in open sunny to partly sunny well-drained habitats.  

This species dies back to the ground in winter and reappears in spring. By early summer it reaches its mature height of 10-12 inches. Pairs of opposite narrowly linear 1-inch long leaves occur along the stem.  Some use this feature to distinguish a separate species, H. tenuifolia, from H. longifolia.  I have chosen to lump the two together as many taxonomists do although there are some differences. Flowering occurs in early summer atop the branched stems. These flowers occur in cymes, are about 1/4-inch wide and composed of 4 fused light lavender to white petals.  These occur on noticeable stalks in H. tenuifolia, but on much shorter ones on H. longifolia.  Once pollinated, small capsules are formed. This species is easily propagated by seed sown shortly after ripening.

Long-leaved summer bluet is a close relative of the commonly encountered innocence (H. procumbens) and shares some of those "demure" characteristics. Its small flowers are pollinated by small bees and other small invertebrates, but it is not grown commercially by nurseries affiliated with FANN - the Florida Association of Native Nurseries. It is occasionally offered for sale by northern native plant nurseries, but it is not the form native to Florida and the south and is unlikely to prosper here.

Narrowlweaf Vervain - Verbena simplex

 

Narrowleaf vervain (Verbena simplex) is a rare plant in Florida, having only been vouchered from Jackson County in the northcentral Panhandle.  It occurs throughout much of the eastern half of the US, however, and is common throughout.  Throughout its range, it is most often found in full sun, dry-mesic to dry conditions, and gravelly to sandy soil. 

This herbaceous perennial dies back to the ground in the winter and reemerges again in spring, eventually reaching a mature height of about 2 feet on a slender erect stem.  It often branches near the base, while above it is unbranched or sparingly branched. The stems are glabrous or short-pubescent; pairs of opposite leaves occur at intervals along these stems. The narrow leaves are 1¼–4" long and less than ½" across; they are narrowly oblanceolate or narrowly elliptic in shape and smooth to coarsely toothed along their margins. There are more teeth toward the tips of the leaves than at their bases. The leaves taper gradually into petiole-like bases. Their upper surfaces are pale to medium green and glabrous or sparsely short-pubescent.

Flowering occurs in late spring to summer at the ends of the stems in spike-like racemes.  There is only one raceme per stem. Only a few flowers bloom at the same time, beginning at the bottom and ending at the top of each raceme. Individual flowers are up to ¼" across, consisting of a lavender to nearly white corolla with 5 spreading lobes, a short tubular calyx with 5 teeth, 4 inserted stamens, and a pistil with a single style. At the base of each flower, there is a lanceolate leafy bract that is about the same length or a little shorter than the calyx. The blooming period occurs for about 2 months. Afterwards, the flowers are replaced by nutlets (4 per flower). These nutlets are oblongloid, somewhat flattened, and about 1/8" long.

All vervains are of interest to pollinators, especially bees.  It is the host for the verbena moth.  There are 7 native verbenas in Florida and 5 that are not.  None are currently in propagation by members of FANN - the Florida Association of Native Nurseries.

Hairy Skullcap - Scutellaria elliptica -

 

Hairy skullcap (Scutellaria elliptica) is one of 13 native members of this very widespread genus.  This species has a limited distribution in Florida - occurring only in 11 north Florida  counties, but occurs widely north of us throughout much of the Midwest and from east Texas to Delaware and Pennsylvania across the Coastal Plain.  Throughout its range, this perennial mint is found in partly shady woodland understories in a variety of soil types, often near streams, but never in poorly drained conditions. 

It dies back to the ground in winter and reemerges again in early spring. It reaches its mature height of 2.5 feet by late spring and the flowers appear by early summer.  They are typical for the genus. The purple and blue flowers bloom from May to July in a 4-inch long raceme. Individual flowers are up to 3/4 inches long and 2-lipped with the upper one hooded and the lower one having white blotches. The calyx has long, spreading glandular hairs.

Hairy skullcap gets its common name from its distinctive foliage. The green leaves are 1.5-3 inches long and 3/4 to 1.5 inches wide. Margins are crenate to serrate, the shape is lanceolate-oblong to oval, the base is rounded to broadly wedge-shaped (cuneate) and the tip is blunt. The underside of the leaf is paler with hairs. The upper surface is dotted with glands. These are quite visible in the photos above.

Skullcaps are hosts for several species of moths and they are of special interest to bees that can squeeze into the hooded blooms. Despite the fact that this genus contains a great many ornamental and easy to grow wildflowers, only a few of Florida's native species are currently available commercially. Hairy skullcap is not one of them.  It is rarely offered by native nurseries outside of Florida.

Hairyjoint Meadow Parsnip - Thaspium barbinode - Update

Hairyjoint meadow parsnip (Thaspium barbinode) is a rare-in-Florida member of the carrot family, vouchered only from Jackson County in the north-central Panhandle with several other possible records elsewhere from Walton and Duval counties - all in extreme north Florida.  It is common to our north, however, and is recorded throughout most of the eastern half of the U.S.  Throughout its range, it is found in moist forested areas, and along streams and ponds and occasionally prairies in full sun to partial shade although shade may impact its growth and number of blooms. It is a perennial that dies back to the ground in winter and reemerges in spring.  

This is a robust wildflower that will eventually reach a mature height of 4-6 feet.  The stems and stem branches have noticeably stiff hairs which give it its common name, but these are not easily seen unless looked at close-up. Like many other members of the carrot family (Apiaceae), it has compound leaves.  They alternate along the stem, but are most abundant near the base,  Each is toothed, 1-2 inches across and up to 1 inch wide.  Leaves ascending the main stem become smaller, and all are minutely "hairy" - especially along the veins and edges.

Flowering occurs in spring.  The umbels of bright yellow flowers in clusters of 10-20 flowers each, are 1-2 inches wide. The tiny individual flowers are all stalked and comprised of five petals that fold inwards. Pollinated flowers form brown oblong seeds by late summer that often remain attached to the stems even as the stems die and fall to the ground.  These can be collected and sown.

I have not cultivated this species previously,  The above photos were taken of plants I purchased from a native plant nursery north of Florida.  It is reported that hairyjoint meadow parsnip is tolerant of a wide variety of soils and growing conditions though it prefers moist (not wet) soil and at least half-day sun.  As a member of the Apiaceae, it is a host for the eastern black swallowtail.  It also attracts a variety of pollinators to its flowers.

Mauve - Abutilon hulseanum

 

Mauve flower

Mauve (Abutilon hulseanum) is one of only two members of this widely occurring genus native to Florida.  The other member, coastal Indian mallow (A. permolle) has been vouchered only from extreme south Florida with a disjunct collection from Manatee County while mauve  has a sporadic distribution throughout peninsular Florida.  It also is reported from Louisiana, Texas, Mexico and the West Indies.  According to Kew Gardens, it is originally from Central America and probably Cuba and Florida.   After going through the photos and labels for specimens in the SIEnet database, the only occurrences in Florida that were convincingly in natural systems (as opposed to highly disturbed areas) were on shell mounds, dunes, and similar coastal sites.  Hence, its true natural distribution in Florida is likely confined to the west coast of the state. Regardless, throughout its current range it is most common to disturbed upland sites in full to partial sun.  In short, it is somewhat weedy by nature. That, of course, is not a value judgement but a statement of its ecological niche.

Mauve gets its rather drab common name from the color of its blooms. As can be seen in the photo above, the five petals (the standard number for plants in the Malvaceae) are a rosy pink in color.  These often start out as yellowish before they assume this color. The blooms are produced near the tops of the stout, almost-woody stems, from winter through late spring in Florida, though sporadic flowering can occur later in the year.  

Mauve is a perennial that reaches about 6 feet tall at maturity.  The erect stems are covered by stiff hairs and are rough to the touch.  Elongated stipules are present at the base of the petiole where it attaches to the stem and the leaves (like many members of this family) are heart-shaped and solitary.  They are normally about 2-3 inches long.

The seed capsules that form after flowering are technically called a schizocarp.  These turn dark brown to almost black at maturity and split open along the carpal lines.  Each contains 4-6 seeds per carpal.  

Mauve flowers attract the attention of a wide variety of pollinators, but it is not known as a host to any butterfly or moth native to our state.  Those that have incorporated it into their landscapes report that it can spread by seed if not contained, but it can make a useful and interesting addition if some care is taken to remove the seed capsules before they mature and split open.  This plant is easy to grow and forgiving of a wide variety of landscape settings except too much shade and wet soils.  It is infrequently offered by native nurseries affiliated with FANN - the Florida Association of Native Nurseries.
