Vegetative Growth
8-12 monthsPlants develop dense clumps of foliage with increasing height and spread
Water during dry spells. Remove any dead growth. No fertilizer needed unless soil is very poor.
Flowering/Seedhead Development
2-4 monthsDelicate flower spikes emerge above foliage, transitioning to ornamental seed heads
Enjoy the full visual display. Do not deadhead if you want seeds to mature and self-sow. Seed heads provide winter interest.
Dormancy/Winter Interest
3-5 monthsFoliage takes on warm tones (tan, bronze, red), seed heads persist and become decorative
Leave growth standing for winter interest and wildlife shelter. Cut back in late winter to early spring before new growth emerges.
Renewal/Spring Growth
2-4 weeksNew shoots emerge from the base as temperatures warm
Cut back old growth to 2-3 inches if not done in late winter. Clear debris. Watch for new growth to break dormancy.
