Vegetative Growth

3-4 weeks

Plant develops branching stems and bushy structure, no flowers yet

Pinch tips to encourage branching and fuller form. Maintain bright light and moderate fertilizing. Gradually acclimate to outdoor conditions if starting indoors.

Budding & Early Flowering

2-3 weeks

Flower buds appear at stem tips; first delicate purple and white flowers open

Begin regular feeding with balanced or slightly phosphorus-rich fertilizer every 1-2 weeks. Ensure consistent moisture and full sun exposure.

Peak Flowering

Abundant bicolor flowers blanket the plant; continuous blooming throughout season

Deadhead spent blooms regularly to encourage more flowering. Fertilize every 1-2 weeks. Monitor for pests and maintain consistent watering schedule.

Decline/Winter Dormancy

Varies by climate

Flowering slows as temperatures drop and days shorten in fall/winter

In frost-prone areas, treat as annual and discard, or bring containers indoors. In zones 10-11, reduce watering and fertilizing. Prune lightly in spring to rejuvenate.
