Horticultural Information

NCBG trait

Intro: Erect perennial of bottomland forests, pastures and roadsides.

Stems: Stem a smooth flowering scape from a bulb with fibrous covering.

Leaves: Leaves basal, ascending, grasslike, flattened and solid, 8-15 in. long.

Inforescence:

Flowers: Flowers in a rounded, compact umbel that begins with a sack-like, membranous covering, a dried remnant of which persists at the umbel base. Flowers consist of a mix of light green to reddish, oval bulbils along with several white to pinkish-lavender, long-stalked flowers; each flower up to ½ in. wide and composed of 6 tepals, 6 stamens, and a light green ovary.

Fruits:

Comments: The variety Allium canadense var. mobilense differs from the typical variety (Allium canadense var. canadense) in that the inflorescence consists of all flowers (no bulbils); it is found mostly farther to the south and in states bordering the Gulf of Mexico.

Height: 8-24 in.
