Growth Stages

1

Seed germination

2-3 weeks

Seeds germinate slowly over 10-21 days. Tiny seedlings emerge with cotyledons.

Keep soil moist and cool (60-70°F). Provide bright indirect light. Do not cover seeds completely.

2

Seedling establishment

4-6 weeks

True leaves develop and seedlings grow to 2-3 inches tall with several sets of small, hairy leaves.

Thin seedlings to proper spacing. Keep consistently moist. Begin fertilizing weekly with dilute balanced fertilizer. Provide cooler conditions.

3

Vegetative growth (First year)

3-4 months

Plant develops bushy rosette of hairy foliage. Growth is vigorous with increasing leaf production but minimal flowering in year one.

Water regularly. Apply balanced fertilizer every 2-3 weeks. Pinch tips to encourage bushiness. Mulch in late fall to protect over winter.

4

Blooming (Second year)

8-12 weeks

Delicate double indigo-blue flowers with rose-form petals and pink centers open in dense clusters on branching stems, reaching 12-18 inches tall.

Deadhead spent flowers to encourage continuous bloom. Water consistently during flowering. Apply low-nitrogen fertilizer to promote blooms over foliage.

5

Seed set and decline

4-6 weeks

After heavy flowering, plant begins setting seed. Flowers fade and plant vigor declines as it completes its lifecycle.

Allow some flowers to remain for self-seeding if desired. Collect seed pods before they split. Plant typically dies back after second year.
