1-inch round cluster at the top of a naked stem, made up of 15 to 30 stalked white flowers with 6 tepals (petals) and 6 creamy-tipped stamens. Flowers are urn to bell shaped, about ¼ inch long, usually white, rarely pink, with a distinct purplish midrib down the center of each tepal. At the base of the cluster are 3 bracts, usually with a single vein.
Leaves and stems:
A plant has 1 or 2 flat grass-like leaves, each about 1/16 inch wide and as long as the flowering stalk, alternately attached near the base, sheathing the stem, and may appear to be basal. Stems are smooth and green. Underground are 1 to 3 gray or brown bulbs covered in a fine mesh of fibers.
White Wild Onion is a shorter plant than most other Allium species found in Minnesota, and most other prairie Allium species more consistently have pink flowers. A western species, Minnesota is on the eastern edge of its range and it's found primarily in dry prairies in counties near the Dakota border. All Allium species were formerly in the Liliaceae (Lily) family, but are now in Alliaceae (Onion).
