Growth Stages

1

Seed Germination

1-2 weeks

Tiny seeds begin sprouting; seedlings are very delicate with two small cotyledons visible.

Keep soil consistently moist but not waterlogged. Provide good air circulation to prevent damping-off. Germination occurs in 7-14 days at temperatures of 55-70°F.

2

Seedling & Establishment

4-6 weeks

Small plants develop true leaves and establish a shallow root system. Creeping stems begin forming.

Thin seedlings to proper spacing. Water gently to avoid disturbing roots. Do not overwater. Begin light fertilizing if in poor soil.

3

Vegetative Growth

6-8 weeks

Plant develops dense foliage with elongated oval leaves and creeping stems spread across soil surface.

Allow stems to sprawl and root along the ground. Remove competing weeds. Apply mulch lightly around (not on) the plant. Light fertilizing monthly with balanced fertilizer.

4

Flowering

6-10 weeks

Delicate bright blue flowers with pink and white centers bloom in clusters on upright stems above foliage.

Deadhead spent flowers to encourage more blooms and prevent excessive self-seeding. Water during dry periods. Flowers typically appear in spring and early summer.

5

Seed Production & Dormancy

4-8 weeks before dormancy

Flowers fade and develop small round seed capsules. Plant begins to decline in heat. Dies back in winter in colder zones.

Allow some flowers to remain for seed production if desired. Cut back after flowering to tidy appearance. In fall, cut back remaining growth to 2-3 inches.
