Seedling
2-3 weeksTiny seedlings with two cotyledons emerge; very delicate and slow-growing
Maintain high humidity and consistent moisture. Use a heat mat (70-75°F). Provide bright, indirect light. Thin seedlings to prevent overcrowding.
Vegetative
3-4 weeksPlant develops true leaves and bushy growth with 4-6 inches of compact foliage
Pinch growing tips to encourage bushier, more compact growth. Fertilize every 2 weeks with balanced fertilizer. Maintain moderate soil moisture.
Budding
2-3 weeksFlower buds form at branch tips; plant is 8-12 inches tall and densely foliated
Continue regular fertilization. Switch to higher phosphorus fertilizer to promote flowering. Maintain consistent moisture and sunlight.
Flowering
8-12 weeks (can extend into fall/winter indoors)Dense clusters of tiny, fragrant purple flowers bloom at branch tips; highly ornamental
Deadhead spent flowers regularly to encourage continuous blooming. Maintain consistent watering and feeding. Monitor for pests.
Harvest/Propagation
Ongoing through seasonFlowers persist for months; plant can be overwintered indoors or propagated from cuttings
Take 3-4 inch softwood cuttings in late summer for winter propagation. Reduce watering and stop fertilizing if overwintering. Can be cut back by half for rejuvenation.
