Establishment
First 12 monthsYoung shrub with sparse branching and limited leaf coverage
Water consistently to establish deep root system. Mulch around base to retain moisture and regulate soil temperature. Avoid heavy fertilization.
Vegetative Growth
Year 2-3Rapid stem and leaf development, plant fills out with increasingly dense branching
Continue regular watering during dry spells. Prune lightly to shape if desired. Foliage color becomes more pronounced as plant matures.
Flowering
2-4 weeks (late spring)Clusters of small white, pink, or rose flowers appear on branch terminals in late May to early June
Blooms appear on old wood, so prune after flowering if needed. Deadheading is optional as seed pods are ornamental.
Fruiting & Seed Pod Development
Summer through winterFlowers fade and reddish seed pods develop, providing decorative interest through fall and winter
Allow seed pods to remain on plant for visual interest and wildlife food source. No deadheading necessary unless desired.
Dormancy & Bark Exfoliation
Fall through early springLeaves drop in fall; distinctive exfoliating bark becomes most visible, peeling in thin layers to reveal inner bark colors
Winter interest is high with visible branch structure and peeling bark. Prune in late winter (February-March) if renewal pruning is desired.

Harvest Tips
Not harvested for food. For ornamental use, branches with colorful foliage can be cut for indoor arrangements in fall. Bark naturally exfoliates and falls off—collect attractive pieces for dried arrangements if desired. Flowers and seed pods can be harvested for dried arrangements in summer.
