PLACEMENT & CULTIVATION

A must for wildflower gardens combined with grasses and coneflowers and valuable in the cutting garden and border for mid-summer through fall bloom. Deadhead for more flowers and mulch to conserve soil moisture during high summer. May overwinter in zones 5-8, but most often grown as an annual. Self-sows.
1" a week. Tolerates some drought once established, but blooms better with regular water.
Prior to planting, mix in about 2" of compost or organic granular fertilizer.
