Seedling
2-3 weeksSmall plants with 2-4 true leaves emerging; delicate appearance with thin stems
Provide bright light, maintain consistent moisture without waterlogging, maintain 65-70°F for optimal germination
Vegetative Growth
2-3 weeksPlants develop multiple stems and foliage; compact bushy shape begins to form
Pinch off growing tips to encourage branching and bushier growth, water regularly, fertilize every 2-3 weeks with balanced fertilizer
Flowering Initiation
1-2 weeksFlower buds appear at branch tips; distinctive clustered umbel formations develop
Continue light pinching if plants are still leggy, reduce nitrogen fertilizer to promote flowering, maintain consistent watering
Full Bloom
6-12+ weeks (continuous with deadheading)Abundant clustered flowers in various colors open continuously; dense flower coverage across plant
Deadhead spent flowers regularly to encourage more blooms, water at soil level to avoid wetting flowers, apply balanced or slightly phosphorus-rich fertilizer weekly
Decline/Overwintering
Varies by climateFlowering slows in cold or hot stressed conditions; plant may become leggy
In zones 9-11, cut back to 6 inches and reduce watering for overwintering, in other zones treat as annual and collect seeds or take cuttings

Harvest Tips
Deadhead spent flower clusters regularly by pinching them off just below the base to promote continuous blooming and compact growth. Cut stems for arrangements in the morning when flowers are fresh. Collect seed from spent flower heads if desired by allowing them to dry on the plant, then store in cool, dry conditions.
