Vegetative Growth
3-4 weeksDevelops compact, mounding form with narrow, blue-green linear foliage; plant grows 8-12 inches tall and wide
Maintain bright light; allow soil to dry slightly between waterings; transplant when 2-3 true leaves appear; pinch seedlings at 4 true leaves to encourage bushiness
Bud Formation
2-3 weeksDense clusters of small buds appear at stem tips; buds begin showing the characteristic picotee color pattern
Provide consistent moisture; apply balanced fertilizer (10-10-10) every 2 weeks or slow-release at planting; ensure full sun exposure
Flowering
6-12+ weeksAbundant ruffled double flowers with picotee coloring bloom continuously; flowers fragrant and 0.75-1 inch across
Deadhead spent flowers regularly to encourage continuous blooming; reduce fertilizer nitrogen to prevent excessive foliage; maintain consistent watering
Decline/End of Season
VariableFlowering diminishes in extreme heat (above 85°F) or frost; plants may decline in late summer heat or after first frost
In cool climates, continue deadheading through fall; in hot regions, provide afternoon shade and consistent moisture to extend bloom; treat as annual in zones 8-10
