Vegetative Growth
5-6 monthsPlant expands into a dense mound of fine, thin green foliage, typically 18-30 inches tall; no flowers present.
Maintain moderate watering during hot growing season. No deadheading necessary. Begin to reduce water frequency as plant matures.
Flowering & Inflorescence
2-3 monthsDelicate airy flower panicles emerge above the foliage in late September through November, displaying purple or reddish hues; panicles are open and wispy.
Do not deadhead; allow flowers to persist for ornamental value through winter. Reduce irrigation as flowering begins. Avoid fertilizing.
Dormancy
3-4 monthsFoliage browns and withers; plant becomes dormant in winter; persistent seed heads and dried stems provide winter interest and shelter for wildlife.
Do not cut back until late winter or early spring. Leave standing through winter for landscape interest and wildlife habitat. No water needed.
Spring Regrowth
4-6 weeksFresh green growth emerges from the crown as soil warms; old growth should be removed before or as new growth appears.
Cut back plants in late February to early March to 4-6 inches above ground. Rake out old debris. Begin moderate watering as growth accelerates.
