Seedling
2-3 weeksTiny seedlings with narrow cotyledons and developing true leaves; fragile and delicate
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to 3-4 inches apart to prevent damping off.
Vegetative Growth
3-4 weeksCompact, bushy plants developing linear gray-green foliage; no flowers yet
Pinch growing tips when 4 inches tall to encourage branching and fuller shape. Maintain consistent moisture and full sun. Feed with balanced fertilizer every 2-3 weeks.
Bud Formation
2-3 weeksDense clusters of small, tight buds forming at branch tips; foliage becoming denser
Continue regular watering and fertilizing. Ensure excellent air circulation to prevent fungal issues. Do not overwater.
Flowering
6-12 weeksAbundant picotee purple flowers with white centers and purple-edged petals; fragrant blooms opening progressively
Deadhead spent flowers regularly to encourage continuous blooming. Reduce nitrogen fertilizer, increase phosphorus for more flowers. Water at base only.
Decline
Variable, until frost or extreme heatFlowering slows in extreme heat or cold; plant vigor decreases; seeds may develop if flowers not deadheaded
In hot climates, provide afternoon shade to extend bloom. In cold regions, mulch or treat as annual. Allow some flowers to set seed if desired for self-sowing.
