Airy pink flowers on wiry stems rise and sway through the heat of summer and into fall, drawing butterflies and hummingbirds without demanding fussing. Full sun and well-draining soil are all this perennial asks; once established, it tolerates drought and poor fertility.

Plant in March for bloom by June, or grab one in September to carry color through the first frost. Thin, wispy stems look best massed in groups or threaded through the middle border where their movement won't be lost.
