. It prefers a position in full sun. '' Allium narcissiflorum'' is very similar to ''A. insubricum'' but found at higher elevation in the mountains. In ''A. insubricum'', the umbel is nodding (hanging downward) at flowering time and remaining nodding when the seeds are mature. In ''A. narcissiflorum'', however, the umbel is nodding at flowering time but erect at maturity. Like most bulbous plants it is usually planted as a dry bulb in the autumn. However, it is also possible to grow from seed.
