Establishment
4-8 weeksYoung plants are small with thin, delicate foliage beginning to form tufts
Water regularly to establish deep roots. Protect from extreme heat and wind. Mulch lightly around base.
Vegetative Growth
8-12 weeksDense mounding growth with fine-textured, dark green foliage becoming more substantial
Maintain consistent moisture. Remove any dead or damaged foliage. No fertilizer needed; benefits from minimal fertility.
Flowering/Seed Head Production
4-6 weeksDelicate panicles of small, brownish flowers emerge above the foliage, creating airy texture
Provide adequate water during this stage. Allow seed heads to develop fully for ornamental interest. Do not deadhead if you want seeds.
Maturity
Throughout growing season and winterFull-sized mound (12-18 inches tall) with developed seed heads that persist through season
Minimal care needed. Leave seed heads for winter interest. Do not overwater. Divide if clumps become too large.
Dormancy/Winter
3-4 monthsFoliage may brown slightly in cold climates but maintains structure; seeds may disperse naturally
Leave foliage standing for wildlife habitat and visual interest. Cut back in late winter or early spring before new growth.
