Propagation of Allium acuminatum Hook. var. cuspidatum Fern.
Allium acuminatum Hook. var. cuspidatum Fern. can be propagated through both sexual and asexual methods. The following are the most commonly used propagation methods:
1. Seed Propagation
Seeds of Allium acuminatum Hook. var. cuspidatum Fern. can be obtained from mature plants during the flowering season. The seeds are small and can be sown directly in the garden bed or started indoors in pots or trays. The best time for outdoor sowing is in late fall or early spring.

Bulb division should be done during the dormant season, which is in late summer or early fall. To divide the bulbs, use a sharp knife to slice through the bulb and create smaller sections with some roots attached. The sections with roots can then be planted at the desired spacing in the garden bed.
3. Bulbils Propagation
Bulbils are small bulbs that grow at the base of the parent bulb. They can be used to propagate Allium acuminatum Hook. var. cuspidatum Fern. by planting them directly in the garden bed during the growing season or by starting them indoors in pots or trays.
