Establishment
3-6 monthsSmall transplant with fine foliage establishing new root system
Water regularly but allow soil to dry between waterings. Protect from extreme heat and wind initially. Avoid fertilizing; plant prefers poor soil. Do not overwater.
Vegetative Growth
6-12 monthsPlant develops dense, bushy form with increasing branch structure; fine, linear foliage becomes more pronounced
Reduce watering frequency as plant establishes. Light pruning can encourage bushiness. No fertilizer needed. Mulch lightly with sand or gravel.
Flowering
8-16 weeks, typically spring-summerSmall white, cream, or pale pink flowers appear in dense clusters along stems; very fragrant; attracts bees and other pollinators
Maintain minimal watering. Do not deadhead unless shaping is desired; spent flowers add interest. Avoid pruning during heavy bloom to maximize flowering.
Post-Bloom & Seed Set
4-8 weeksFlowers fade and develop small seed capsules; plant growth may continue if conditions permit
Light pruning after flowering promotes next season's blooms and maintains compact form. Allow some spent flowers to remain for wildlife benefit.
Dormancy/Rest
4-6 monthsGrowth slows or pauses during cooler months or dry season; foliage remains evergreen and ornamental
Minimal to no watering in winter or dry season. No fertilizer. Prune only for shape if needed. Monitor for occasional pests or disease.
