Seedling
2-3 weeksTiny green shoots emerge with narrow cotyledons; plants develop first true leaves within 2-3 weeks
Keep soil consistently moist but not waterlogged. Provide bright light and good air circulation to prevent damping off. Thin seedlings to proper spacing.
Vegetative Growth
4-6 weeksPlant develops bushy foliage with thin, needle-like gray-green leaves on upright stems; no flowers yet
Pinch back growing tips when 4-6 inches tall to encourage branching and bushier growth. Remove any dead or diseased foliage. Water at soil level.
Bud Formation
2-3 weeksFlower buds begin forming at stem tips; buds are tight and wrapped in sepals
Apply balanced flowering fertilizer (lower nitrogen, higher phosphorus). Continue regular watering. Support tall stems with stakes if needed.
Flowering
3-6 weeks per flower, staggered bloomingBuds open to reveal fully double flowers with crimson-red petals edged in white or pale pink; strong clove-like fragrance
Deadhead spent flowers to encourage continued blooming. Water consistently. Avoid overhead watering. Cut flowers when petals just begin to reflex for longest vase life.
Senescence
Variable, depends on climateFlowers fade and petals drop; plant may decline in summer heat or cool season if not treated as perennial
