Stake tall varieties if in windy locations. Deadhead spent flowers to encourage more blooms. Water during dry spells.
Peak Flowering

Deadhead regularly for continuous flowering, or leave some flowers for seed production. Water during drought. No fertilizer needed.
Seed Production & Decline

Fun Facts
- 🌱 Coneflower is native to the prairies and woodlands of North America and was used medicinally by Plains Indians long before European settlement.
- 🌱 The distinctive spiky orange-brown central cone gives the plant its common name and serves an important ecological function—it's perfectly designed for bees and butterflies to land on while foraging.
- 🌱 Coneflower blooms longer and more prolifically with regular deadheading, but leaving some flowers to set seed ensures year-round wildlife habitat and allows for easy self-seeding to fill in garden spaces.
