Seedling/Bulblet Establishment
2-4 weeksTiny green shoots emerge from bulblets or seeds, developing first 1-2 narrow leaves. Root system establishes in soil.
Keep soil consistently moist but not waterlogged. Protect from heavy foot traffic. Thin crowded seedlings to spacing distance.
Vegetative Growth
6-10 weeksPlant develops multiple thin, upright green leaves resembling grass or chives. Bulbs remain underground, enlarging slowly.
Water regularly during dry spells. Do not fertilize heavily; avoid nitrogen-rich fertilizers that promote foliage over bulb development. Mulch to retain moisture and moderate soil temperature.
Flowering
3-4 weeksDelicate umbels of small pink, white, or purple flowers appear atop thin stems. Flowers are star-shaped and attract pollinators.
Allow some plants to flower for seed production and natural propagation. Deadhead some flowers to redirect energy to bulb formation. Maintain consistent moisture.
Seed Development & Ripening
4-6 weeksFlowers fade and develop into small round seed capsules. Above-ground foliage begins yellowing and drying as the plant focuses on seed maturation and underground bulb enlargement.
Reduce watering as foliage dies back. Allow seed heads to dry fully before harvesting seeds. Bulblets are sizing up underground.
Dormancy & Harvest
Ongoing until next spring emergenceAll foliage dies back to ground level. Underground bulbs and bulblets reach mature size. Plant enters dormant period until next growing season.
Harvest bulbs when foliage completely dies back (summer). Cure bulbs in dry location for 2-3 weeks before storage. Store in cool, dry place.

Harvest Tips
Harvest bulbs in summer (June-July in northern zones) once foliage dies back completely. Dig carefully to avoid damaging small bulbs. Collect seeds from dried flower heads in late summer by gently crushing seed heads. Green shoots can be harvested sparingly in spring for culinary use—cut outer leaves and allow plant to continue growing. Cure dried bulbs in warm, airy location for 2-3 weeks before storage.
