Growth Stages

1

Seed/Germination

7-14 days

Tiny seeds germinate in warm soil; first true leaves emerge within 7-10 days

Keep soil warm (70-75°F) and consistently moist but not soggy. Provide good light once sprouted. Thin seedlings to prevent crowding.

2

Seedling to Transplant

3-4 weeks

Seedlings develop 2-4 true leaves and grow small but sturdy; ready for larger containers

Provide bright light (grow lights 2-3 inches above seedlings). Fertilize weakly with balanced liquid fertilizer every 1-2 weeks. Harden off before transplanting outdoors.

3

Vegetative Growth

2-3 weeks after transplanting

Plant establishes compact, mounding form with increasing leaf development; 6-10 inches tall

Pinch terminal buds when 4-6 inches tall to encourage bushier growth (optional but recommended). Water consistently. Fertilize every 2-3 weeks with balanced or slightly lower-nitrogen fertilizer.

4

Flowering

8-12 weeks (from first flower until frost)

Abundant pure white double flowers bloom prolifically on compact plants; continuous bloom through season

Deadhead spent flowers to encourage more blooms (optional; this variety is self-cleaning). Water at soil level to reduce fungal issues. Reduce nitrogen fertilizer; use bloom-boosting formula if desired.

5

Late Season/Decline

Until frost (typically 4-8 weeks depending on region)

Flowering continues until first frost; plants gradually slow production in fall cool temperatures

Allow some flowers to fade for seed collection if desired. Continue deadheading for continuous blooms. Plant remains vigorous until hard frost.

Harvest Tips

This cultivar is grown for ornamental flowers rather than seeds. Deadhead spent blooms regularly to maintain continuous flowering and plant appearance. For seed collection, allow flowers to fade and dry on plant; collect seed heads when brown and papery, then dry indoors before storing.
