Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with first true leaves appearing within 7-10 days under moist conditions and cool temperatures.

Keep soil moist and maintain temperatures around 60-70°F. Provide indirect light. Thin seedlings to 6 inches apart.

2

Seedling & Vegetative Growth

2-3 weeks

Plants develop true leaves and bushy foliage. Stems remain tender and growth is compact and spreading.

Water regularly to keep soil moist. Do not let soil dry out completely. Begin hardening off outdoor seedlings 7-10 days before transplanting.

3

Flowering

4-8 weeks

Small, delicate cup-shaped flowers appear in white, lavender, and purple with distinctive spotting or veining patterns. Blooms emerge continuously with proper care.

Deadhead spent flowers to encourage continuous blooming. Reduce watering slightly but keep soil evenly moist. Provide afternoon shade in hot climates.

4

Peak Bloom

2-4 weeks

Plant reaches full flowering capacity with abundant blooms covering the foliage. Color intensity is strongest during cool weather.

Continue deadheading. Maintain consistent moisture. Watch for spider mites and aphids in stressed plants. Expect blooms to decline in extreme heat.

5

Seed Production & Decline

Variable, typically 2-3 weeks before decline

If left undeadheaded, flowers develop into small seed pods. Plant may slow flowering or decline as temperatures rise.

Allow some flowers to go to seed for self-seeding next year. As plant declines, remove and compost. Save mature seed pods in cool climates.

  • and

    Remove by hand in early morning. Use diatomaceous earth or copper tape barriers. Keep area dry during day.
