Seedling
2-3 weeksSmall plants with initial lobed cotyledons, developing true leaves with characteristic lobed margins
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksRapid stem and leaf development with increasingly larger lobed leaves, bushy growth habit forming
Maintain moderate watering. Fertilize monthly with balanced fertilizer. Prune to encourage branching and bushiness.
Fruiting & Seed Production
4-6 weeks after floweringDevelopment of bristly capsules containing seeds; mature fruits have distinctive hooked hairs
Allow fruits to dry on plant if collecting seeds. Seeds will self-disperse; deadhead if preventing self-seeding. Reduce nitrogen fertilizer.
Dormancy/Winter
2-4 monthsReduced growth in cooler months; may lose leaves in zones below 10 or during temperature drops
Reduce watering significantly. Protect from frost in marginal zones; mulch heavily or move containers indoors. Prune dead growth in spring.
