Tennessee coneflower is endangered in its native habitat. Bee and butterfly flower. Flower shape is different from common purple coneflower: the rays go straight out (or even curl up) instead of down, and are narrower and typically paler. The whole plant is smaller. We like it a lot, and keep starting new plants from seed to replace the plants, which only last a few years each.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. One or more images of this plant are included in my stock photo catalog About my plant portraits

- Seed from '12 garden, cold-stored; selected plumpest seeds. Baggy 35F (13w) - 70F (100%G, 4d)
Appears to benefit from a long cold stratification period. Seedlings are finnicky - typically, not all survive.
