Purple Coneflower - Echinacea purpurea

Purple coneflower (Echinacea purpurea) is a common wildflower throughout much of the eastern half of North America, but exceedingly rare in Florida.  Resident to only a few limestone glades in Gadsden County, purple coneflower is listed here as a state endangered species.
In these glades communities, it occurs in open to partially sunny openings, in well-drained soil that has a rather high pH.  These are not the same conditions this plant is found in further north. Purple coneflower is a perennial that dies back completely to the ground in winter. A basal rosette of noticeably toothed, arrow-shaped leaves emerges in spring. Each leaf is deep green and up to 6 inches long.  They are rough to the touch. Multiple flower stalks arise from inside these rosettes in spring and flowering occurs over a protracted period in summer.  The large showy blooms are several inches across with pink to lavender ray petals and a central disk of spiky greenish brown ones.  Purple coneflower attracts a very diverse assortment of pollinating insects and there is always someting nectaring on it. In sunny areas, these flowers stand several feet tall, but in the shade (like the photos taken above) they can reach 3-4 feet tall.
The vast majority of purple coneflower being propagated here in Florida does not come from Florida stock, which is why so many people tell me that their plants act like annuals. Seed and plants from areas to our north do not perform well in Florida and should be avoided if you do not wish to replant it each spring. Dan Miller, of Trillium Gardens in Tallahassee, has been propagating his purple coneflower from Florida plants. My stock came from his and it has done well in Pinellas County and has lasted now for 2 years without sign of wasting away. The same is true of the specimens photographed above in the landscape of a friend in Gainesville.
In Florida, purple coneflower seems to do best when used in partly sunny locations. It is drought tolerant and does not require limey soils, but do not plant it anywhere that does not drain well.  I like it mixed with other medium-tall wildflowers, in patches of no less than 3 plants, preferably more than 5.  Just make sure your plants come originally from the Florida population. Don't be fooled by those who tell you it came from plants grown in Florida - most of those are not Florida genetic stock, but out-of-state stock grown in a Florida garden. I have tried plenty of those in the past and every time I have, the plants died after the first year.


  1. My sister recently moved to Florida and told me they have lots of flowers in Punta Gorda, Florida and they are really nice.

  2. Just saw this post and got excited about the purple cone flower in my yard. I bought it from the native plant sale at Morningside Nature Center. It has been doing great. I'm wondering the best way to save and start more from seed.

  3. The seed is relatively easily propagated. Sow it no later than the fall, about 1/4 inch deep in a flat with good potting soil. The seed should germinate in no more than 3 weeks. Transplant the seedlings into small pots in the spring. Once they have developed vigorous root systems, plant them in your landscape. If you end up planting them in spring, make sure you keep them watered well until the summer rains return. Good luck. I have some seed this year myself and hope to be able to offer this species by spring 2014.

  4. Script is quite awesome,
    Purple Coneflower very helpful for calm and blissful nature
