Seedling
2-3 weeksTiny seedlings with small linear leaves emerge within 7-14 days. Plants are delicate and require consistent moisture.
Keep soil consistently moist but not soggy. Provide bright light and warm temperatures (70-75°F). Thin seedlings to proper spacing once true leaves appear.
Vegetative Growth
3-4 weeksPlants develop bushy foliage with narrow, lance-shaped leaves. Stems branch out to form a mounding habit, reaching 12-18 inches tall.
Water regularly but allow soil to dry slightly between waterings. Pinch back growing tips when plants are 4-6 inches tall to encourage bushier growth and more blooms.
Flowering
6-10 weeksDense clusters of small star-shaped flowers appear at branch tips, showcasing coral, pink, or salmon petals with contrasting darker centers.
Deadhead spent flowers regularly to extend blooming period. Maintain consistent watering, but reduce if temperatures exceed 90°F. Feed with balanced fertilizer every 3-4 weeks.
Peak Bloom
4-8 weeksPlants are completely covered with continuous flower clusters from mid-summer through fall frost.
Continue deadheading for maximum flowering. Reduce nitrogen fertilizer to avoid excessive vegetative growth at the expense of blooms. Provide afternoon shade in extreme heat.
Seed Set & Decline
Until frostIf flowers are not deadheaded, seed pods form and plant vigor declines. Foliage may yellow or decline in extreme heat.
For continuous blooms, deadhead all spent flowers. If saving seeds, allow some flowers to mature. In zones 8-11, plants may reseed for next year if left unharvested.
