Establishment
3-6 monthsYoung transplant with initial root development and gradual stem elongation
Water regularly but allow soil to dry between waterings. Protect from hard freezes in zone 7. Avoid fertilizing. Stake if necessary in windy locations.
Vegetative Growth
6-12 monthsPlant develops branching structure with narrow, needle-like or small linear leaves; gray-green foliage becomes established
Minimal watering once established. Light pruning after flowering promotes bushier form. Remove any dead or damaged growth in spring.
Pre-flowering
4-8 weeksBranch tips begin producing flower buds; buds develop from late winter through early spring
No fertilizer needed or desired. Ensure full sun exposure. Avoid pruning flower buds. Reduce watering even more.
Flowering
4-6 weeks (peak spring/early summer); may rebloom lightly in fallAbundant magenta-pink flowers with dark burgundy-brown central blotches open along branch tips; flowers are single, papery-textured, and short-lived (1 day each)
Do not deadhead unless improving appearance; plant flowers continuously if blooming period is undisturbed. Allow some flowers to remain for wildlife benefit. No watering needed unless extreme drought.
Post-flowering & Dormancy
3-4 monthsFlowering declines; foliage remains semi-evergreen; plant enters semi-dormant phase in summer heat
Light pruning after flowering to shape and maintain compact form; never hard prune into old bare wood. Resume minimal watering only during severe drought. Prepare for winter protection in zone 7.
