Year 2-3Rapid branch development; increasing foliage density; shrub building structure
Continue regular watering; apply balanced fertilizer in spring; light pruning to shape; remove any crossing or weak branches
Flowering
3-4 weeks, typically May-JuneAbundant tubular pink flowers (sometimes with yellow throat) covering branches; peaks in late spring
Maintain consistent moisture during flowering period; deadhead spent flowers if desired; do not fertilize heavily as excess nitrogen reduces flowers
Fruiting & Seed Development
Summer through early fallSmall dry capsule fruits form after flowering; fruits contain tiny seeds
Allow fruits to remain on plant for wildlife; can collect seeds in late summer if propagation desired
Dormancy & Bark Display
Fall through early springLeaves drop in fall; exfoliating tan and brown bark becomes prominent winter feature
Prune in late winter while dormant for rejuvenation; light pruning acceptable after flowering; maintain shape; no watering needed
