Dormant Tuber
Winter storage, typically 4-6 monthsTubers are stored in cool, dry conditions before planting. They appear as brown, lumpy underground stems with visible eyes or growth buds.
Store tubers at 40-50°F in a dark, dry location. Keep in peat moss or sand to prevent drying. Check periodically for rot and remove affected tubers.
Sprouting & Establishment
3-4 weeks after plantingEyes begin to sprout and roots develop. Above-ground shoots emerge and small leaves unfold. Plant growth is still relatively slow.
Plant tubers after last frost when soil is warm (60°F+). Water moderately to establish roots without rotting tubers. Ensure good drainage. Keep area weed-free.
Vegetative Growth
4-6 weeksThe plant develops multiple stems and numerous compound leaves. Growth accelerates in warm weather. The plant fills out to its characteristic compact, bushy form.
Pinch out the growing tip when plant reaches 6-8 inches tall to encourage branching. Fertilize every 2-3 weeks with balanced or bloom-promoting fertilizer. Provide support stakes if needed. Remove lower leaves as they fade.
Flowering
8-12+ weeks, often until first frostAbundant small, fully double white pompom-like flowers appear at branch tips. Buds continue to form throughout the season as older flowers fade. Plant is at peak ornamental value.
Deadhead spent flowers regularly to encourage continuous blooming. Maintain consistent moisture and fertilize every 2-3 weeks. Watch for pests and diseases. Provide afternoon shade in extremely hot climates (above 90°F regularly).
Decline & Dormancy
2-4 weeks until full dormancyAfter first frost, foliage blackens and dies back. Tubers mature underground and begin dormancy. Plant enters rest phase.
After frost, cut foliage back to 2-3 inches above ground. Dig tubers carefully, let soil dry on them, and remove loose soil. Cure tubers in a cool location for 1-2 weeks before storage. Store in cool, dry conditions over winter.
