How to grow
Plant in spring in well-drained soil — in Florida, give afternoon shade and excellent drainage; it hates wet feet in summer. It's drought-tolerant once established and dislikes being fussed over. Leave seed heads standing through winter for birds and self-seeding.
Water & feeding
Water to establish, then back off — it's a prairie plant that prefers lean, dry conditions. Overwatering shortens its life.
Common problems
- Aster yellows (phytoplasma) — distorted green flowers; pull and destroy
- Powdery mildew in humid shade
- Crown rot in soggy soil
Harvest
Cut flowers just as petals unfurl for bouquets. Deadhead for rebloom, or leave heads for goldfinches — they'll strip every seed by January.
Nerdy fact: Echinacea's immune-boosting reputation comes from alkamides that tingle your tongue — that buzzing sensation is literally the active compounds announcing themselves. Your mouth is a chemistry lab.
