Establishment
4-8 weeksYoung transplant with small stems and limited foliage; plant appears sparse.
Water moderately for first 4-6 weeks to encourage root development. Avoid overwatering. Provide full sun. Protect from harsh winds if young.
Vegetative Growth
6-12 monthsCompact shrub develops woody stems, gray-green narrow leaves, and more branching; foliage is dense and waxy.
Reduce watering frequency. Light pruning after flowering encourages bushiness. No fertilizer needed; low-nutrient soils are preferred.
Flowering
4-8 weeks (late spring to early summer)Abundant crinkled pink to magenta flowers with yellow stamens bloom profusely; flowers are 1.5-2 inches across and ephemeral (lasting one day).

Post-Bloom
3-4 monthsFlowers fade and drop; green seed capsules develop. Plant enters semi-dormancy or reduced growth in summer heat.
Prune lightly after flowering to maintain shape and encourage next season's blooms. Reduce water to minimal levels.
Dormancy/Mature
Several months to ongoingPlant remains evergreen but growth slows significantly in late fall and winter; appears compact and hardy.
Withhold water except in extended drought. No fertilizer needed. Prune only for shape or frost damage. Plant is fully hardy at this stage.
