Growth Stages

1

Dormancy & Root Establishment

12-14 weeks

Bulb is planted in fall and develops roots over winter while remaining dormant underground

Plant in October-November before ground freezes. Ensure good drainage to prevent bulb rot. Mulch lightly after planting for insulation.

2

Emergence & Growth

3-4 weeks

Green shoots and leaves emerge from soil in early spring as temperatures warm; plant develops 18-24 inch tall stems

Remove winter mulch once shoots appear. Water if spring is dry. Apply balanced fertilizer once shoots break ground.

3

Bud Formation

2-3 weeks

Flower buds form at stem tips; visible as small green bumps that gradually enlarge and show color

Continue consistent watering. Stake tall varieties if needed. Protect from strong winds.

4

Flowering

2-3 weeks

Large double flowers open with 4-5 inch blooms displaying numerous pure white petals in peony-like formation

Cut back on overhead watering to prevent petal damage. Deadhead spent flowers if not saving seeds. Cut for arrangements in morning.

5

Senescence & Decline

4-6 weeks

Petals fade and drop; leaves yellow and die back as plant enters dormancy

Allow foliage to remain until completely brown (6 weeks after flowering). Continue light watering. Stop fertilizing.

Harvest Tips

Cut flowers in early morning when buds show color but before fully opening. Cut stems at least 10 inches long. Remove lower leaves below waterline. Change water every 2-3 days. Flowers will continue opening in the vase. For garden display, deadhead spent blooms to encourage plant energy toward bulb storage. Allow foliage to die back naturally for 6 weeks to replenish bulbs for next season.
