Seedling
3-4 weeksTiny rosette of oval leaves appears; plants are delicate and small
Keep soil moist but not soggy. Provide bright, indirect light. Thin seedlings to prevent damping off. Germinate at cool temperatures (60-65°F).
Vegetative Growth
8-12 weeksRosette of crinkled, oblong leaves expands; dense mounding form develops
Water consistently. Begin fertilizing every 2-3 weeks with dilute balanced fertilizer. Pinch tips to encourage bushiness if grown from seed.
Bud Formation
2-3 weeksFlower buds appear on short stems above the foliage rosette; buds are tightly clustered
Maintain consistent moisture. Avoid overhead watering. Continue light fertilizing. Cool temperatures (50-60°F) encourage better blooming.
Flowering
4-8 weeks (spring, some repeat in fall in cool climates)Abundant clusters of small, five-petaled flowers open in vibrant colors; flowers are slightly fragrant
Deadhead spent flowers to encourage continuous blooming. Water at soil level. Protect from hot afternoon sun in warm climates. Apply dilute low-nitrogen fertilizer weekly for sustained bloom.
Post-Bloom & Summer Rest
Summer dormancy until fall/next springFlowers fade; plant may look tired or sparse in hot weather; foliage remains evergreen
Cut back or deadhead heavily. Keep soil moist but allow good drainage. Provide afternoon shade in zones 7-8. Mulch lightly to protect roots and retain moisture for second bloom season.
