Growth Stages

1

Dormancy

3-4 months

Bulb lies dormant underground during winter months with no visible growth

Ensure bulbs are planted 6-8 inches deep in fall; apply mulch for insulation; monitor for excessive moisture which can cause rot

2

Emergence & Vegetative Growth

4-6 weeks

Shoots emerge in spring, developing tall stems with lance-shaped leaves arranged alternately or in whorls

Water consistently as growth accelerates; apply balanced fertilizer; stake tall varieties for support; remove any diseased leaves

3

Bud Formation

2-3 weeks

Flower buds form at stem tips, with buds becoming visible and increasing in size

Continue consistent watering and feeding; provide support stakes if needed; mulch around base to retain moisture and keep roots cool

4

Flowering

3-5 weeks

Flowers open in succession from bottom to top, displaying reflexed orange-red petals with dark purple spots and nodding habit

Deadhead spent flowers but leave stem intact; maintain moisture; stake stems if heavy with blooms; enjoy fragrance; cut for arrangements if desired

5

Seed Development & Senescence

4-8 weeks

Flowers fade after pollination; seed pods develop; foliage yellows and dies back

Allow foliage to die back naturally to rebuild bulb reserves; leave seed pods if collecting seeds; stop fertilizing; reduce watering gradually; apply fall mulch

Harvest Tips

Cut stems for arrangements in early morning when flowers are opening; cut above the lowest set of leaves to preserve bulb energy; allow at least one-third of stem to remain on plant. Seed pods can be collected in fall when tan and dry; let them open naturally to release seeds. Do not remove foliage until it yellows naturally, as it feeds the bulb.
