Growth Stages

1

Dormancy

November-March (4-5 months)

Plant is below ground as a rhizome during winter months.

Mulch heavily with 2-3 inches of leaf mold or compost for insulation. Keep soil from freezing hard. Minimal disturbance needed.

2

Emergence & Vegetative

March-July (4-5 months)

New hairy shoots emerge in spring with alternate lance-shaped leaves along arching stems.

Remove winter mulch gradually as new growth appears. Keep soil consistently moist. Support stems with stakes if needed in windy locations. Feed with balanced fertilizer monthly.

3

Bud Formation

July-August (4-6 weeks)

Terminal flower buds develop at the stem tips, remaining tightly closed.

Continue consistent watering and monthly feeding. Ensure adequate humidity. Watch for pests. Provide shelter from strong winds that may damage buds.

4

Flowering

August-October (8-10 weeks)

Distinctive spotted flowers bloom in clusters, with 6 petals in deep purple-burgundy with yellow throats and burgundy spots. Flowers open sequentially over several weeks.

Maintain consistent moisture. Do not fertilize heavily as it promotes foliage over flowers. Deadhead spent flowers to encourage continued blooming. Cut flowers last 7-10 days in arrangements.

5

Senescence & Dormancy

October-November (4-6 weeks)

After frost, foliage yellows and dies back. The plant withdraws energy to the underground rhizome for winter.

Cut back dead foliage after a hard frost. Apply heavy mulch (2-3 inches) with leaf mold, compost, or pine needles. Reduce water in late fall. Do not fertilize.

Harvest Tips

Cut flowers in early morning when fully opened for longest vase life. Use a sharp knife and cut stems at an angle. Remove lower leaves before arranging. Change water every 2-3 days. Flowers typically last 7-10 days in fresh arrangements. Do not deadhead if you want seeds to develop for propagation; seeds ripen in capsules by late fall.
