Seedling
2-3 weeksTiny green sprouts with first true leaves appearing. Very delicate and slow-growing initially.
Keep soil lightly moist, provide bright indirect light, maintain warmth (65-75°F). Avoid overwatering which causes damping off.
Vegetative Growth
3-4 weeksPlant develops multiple stems and trailing branches with small oval leaves. Growth accelerates as temperatures warm.
Gradually increase light exposure. Begin light fertilizing when true leaves develop. Pinch tips to encourage bushier, fuller growth if desired.
Pre-Flowering
1-2 weeksDense, spreading growth habit becomes evident. Buds begin forming at leaf axils along stems.
Maintain consistent moisture and full sun exposure. Continue balanced fertilizing every 2-3 weeks. Reduce nitrogen to encourage flowering.
Flowering
8-12+ weeks (continuous in warm climate)Abundant fan-shaped flowers with 5 petals (one petal typically smaller) appear along trailing stems. Colors include blue, purple, pink, or white.
Deadhead spent flowers to prolong blooming. Maintain regular watering and fertilizing schedule. Ensure full sun for maximum flower production.
Maturity & Maintenance
OngoingEstablished plant maintains cascading, flowering habit. In warm zones, blooming continues year-round with reduced flowering in winter.
