Growth Stages

1

Seedling

2-3 weeks

Small cotyledons appear within 5-10 days. True leaves develop shortly after.

Keep soil warm (70-75°F) and consistently moist. Provide bright light. Thin seedlings or transplant when first true leaves appear.

2

Vegetative Growth

3-4 weeks

Compact bushy plant develops with multiple stems and lance-shaped green leaves.

Pinch back growing tips at 3-4 inches tall to encourage bushier branching. Avoid overwatering.

3

Bud Formation

2-3 weeks

Small flower buds appear at branch tips. Plant reaches full compact height.

Continue regular watering and maintain full sun exposure. Light feeding with balanced fertilizer optional.

4

Flowering

8-12 weeks until frost

Delicate pastel-colored double and semi-double blooms open continuously. Flowers are 1-1.5 inches across.

Deadhead spent flowers to promote continuous blooming. Water at soil level. Stake if needed in windy locations.

5

Seed Set

2-3 weeks

If flowers are left on plant, seeds develop in central seed pod.

Allow a few late-season flowers to fully mature for seed collection if desired. Most growers deadhead to maintain blooms.
