Growth Stages

1

Dormancy/Planting

Variable, until growth begins

Bulbs are dormant and may appear shriveled. Plant when soil is warm in spring or early summer.

Soak bulbs briefly before planting. Ensure excellent drainage to prevent rot. Store dry bulbs in cool location if not immediately planting.

2

Sprouting

2-3 weeks

Fine, grass-like leaves emerge from soil 2-3 weeks after planting.

Begin gentle watering once shoots appear. Keep soil consistently moist but not waterlogged. Provide full sun.

3

Vegetative Growth

4-6 weeks

Thin, linear foliage develops and elongates, forming a mound of grass-like leaves.

Water regularly during active growth. Feed monthly with balanced or phosphorus-rich fertilizer. Do not overwater.

4

Flowering

6-10 weeks (repeating flushes with proper conditions)

Delicate yellow star-shaped flowers emerge on thin stems above foliage. Flowers are 1-1.5 inches across and typically bloom for 1-2 days per flower.

Maintain consistent moisture; blooms are triggered by warm temperatures and rain-like watering. Deadhead spent flowers to encourage repeated blooming. Provide bright light.

5

Senescence/Dormancy

3-4 months (November-February in Northern Hemisphere)

Foliage yellows and dies back as temperatures cool or moisture is withheld in autumn/winter.

Gradually reduce watering as growth slows. Allow foliage to dry completely; do not cut back until fully brown. Store cool and dry during dormancy.

Harvest Tips

Zephyranthes is grown for ornamental flowers, not harvest. Cut flowers last 1-2 days in a vase. Flowers bloom continuously in warm weather with proper moisture cycling. For seed collection, allow spent flowers to develop seed pods; collect when brown and dry. Allow bulbs to naturalize and multiply; divide every 3-4 years.

Fun Facts
