Product Info
Allegheny Onion (Allium allegheniense )
Onion FamilyBright, magenta flowers differentiate this member of the onion family from the more commonly available Nodding Onion (Allium cernum). Drooping flowers begin opening in July, followed by bead-like seed heads that hold 4, shiny black seeds. Foliage is thin and strappy, typical of the onion family. It has a very narrow native range in the southern Appalachian Mountains, usually growing in lean soils and rocky areas. While it prefers soils with a higher pH, it seems to adapt to average garden soil just fine. It is very drought tolerant and can handle the toughest of soils. In warmer areas, a break from the afternoon sun will make for a healthier plant. Rare in cultivation.
