Establishment
First 4-6 weeks after plantingYoung plant with emerging shoots and developing root system
Keep soil consistently moist. Mulch heavily to retain moisture and regulate soil temperature. Provide afternoon shade in warmer zones
Vegetative Growth
Spring through early summer (8-12 weeks)Robust foliage development with large, deeply lobed elderlike leaves emerging from the crown
Maintain consistent moisture. Apply 2-3 inches of mulch around base. Fertilize monthly with balanced or foliage-promoting fertilizer in growing season
Pre-flowering
Late spring (2-3 weeks)Plant reaches full size; flower buds form at stem tips as days lengthen
Continue consistent watering and mulching. Reduce nitrogen fertilizer to encourage flowering over foliage
Flowering
June-July (4-6 weeks)Feathery plumes of tiny pink, white, or cream flowers rise above foliage, creating airy vertical interest
Maintain moist soil. Deadhead spent flowers if you want to redirect energy, or leave for seed heads. Support tall stems with stakes if needed in windy locations
Post-flowering & Dormancy
August through MarchFlowers fade to brown seed heads; foliage remains attractive. Plant enters dormancy in fall and winter
Leave seed heads for winter interest and wildlife. Cut back dead foliage in early spring before new growth. Reduce watering in winter but never let soil dry out completely
