Discussion | Allium oleraceum is reported from New England, where it is sometimes found on roadsides and other disturbed ground. It persists and is spread easily by the bulbils. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Allium elmendorfii is known only from the Carrizo sands of eastern Bexar, Frio, Wilson, and Atacosa counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
