Growth Stages

1

Dormancy

May-October

Bulbs lie dormant in soil over summer and fall until cold trigger initiates growth

Ensure soil remains relatively dry during summer dormancy; avoid overwatering

2

Root Development

October-February

Roots emerge from bulb base in fall; foliage begins to emerge near soil surface

Provide consistent cool temperatures; light watering if very dry

3

Vegetative Growth

February-March

Strap-like green foliage emerges and elongates in early spring; flower spike begins to form within foliage

Water moderately as growth accelerates; apply low-nitrogen fertilizer if desired

4

Flowering

3-4 weeks (April-May depending on zone)

Dense spike of tiny cobalt-blue fragrant flowers opens from bottom to top; each flower resembles a grape

Deadhead spent flowers to prevent self-seeding if desired; enjoy fragrance; stake if needed in wind

5

Senescence & Foliage Maturation

May-June

Flowers fade; foliage remains green and photosynthesizes to replenish bulb energy reserves

Do NOT cut back foliage; allow it to yellow naturally over 4-6 weeks; continue watering lightly

Harvest Tips

Muscari 'Blue Magic' is ornamental and not harvested for food. Cut flower spikes for indoor arrangements when the lower flowers are open but upper buds remain tight. Flowers last 5-7 days in a vase with fresh water. After flowering, allow foliage to remain on plant until it yellows naturally (4-6 weeks) to build bulb reserves for next year; do not remove or tie up foliage.

Fun Facts
