Just after the petals emerge

Common name Tennessee coneflower Family asteraceae Life cycle perennial (Z5-9) Flowers purple (summer) Size 2' tall, 18" wide Light full sun Cultural notes all soils. drough-tolerant From seed 10-12 weeks cold, to warm for germination detailed seed-starting info below Seed ripens late October 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.
