Allium insubricum is a plant species endemic to the Lombardy region in northern Italy. It is named for Insubria, the ancient name for the area around present-day Milan. The species is, however, widely cultivated as an ornamental because of its strikingly beautiful flowers. 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.
