Establishment
4-8 weeksYoung plant developing root system and establishing growth pattern. Minimal branching initially.
Plant in spring in well-draining soil. Keep soil consistently moist but not waterlogged for first 4-6 weeks. Protect from direct intense sun initially. Avoid fertilizing for first month.
Vegetative Growth
6-12 monthsPlant develops multiple stems and foliage; elongated leaves appear along branches. No flowers yet.
Apply balanced fertilizer (10-10-10) monthly during growing season (spring-summer). Pinch branch tips to encourage branching. Increase watering as plant grows. Full sun exposure critical.
Budding & Flowering
8-16 weeksTerminal clusters of flower buds form at branch tips. Buds develop over 2-3 weeks, then open into fragrant white flowers with yellow centers.
Shift to higher phosphorus fertilizer (10-30-10) to promote flowering. Maintain consistent watering; do not allow soil to dry completely. Flowers last several days and continue blooming in succession.
Peak Bloom
4-8 weeksMultiple flower clusters open simultaneously, creating abundant white blooms with golden-yellow throats. Plant at its most ornamental.
Continue regular watering and fertilizing. Remove spent flowers to encourage continued blooming. Maintain full sun exposure. Monitor for pests attracted to flowers.
Dormancy
2-4 monthsLeaves yellow and drop naturally as temperatures cool or seasonal changes occur. Plant enters rest period with bare or sparse branches.
Dramatically reduce watering—water only once monthly or until soil is completely dry. Stop all fertilizing. Move container plants to protected location if frost threatened. Dormancy is normal and necessary for next year's flowering.
