Ecology & Habitat

Description

Fringed Onion has 2 leaves that are concave in cross-section, 1-3 mm wide, and up to 15 cm long. Bulbs are ovoid in shape with a gray-brown outer coat. The flower stalk is up to 15 cm tall and usually shorter than the leaves. There are 2 membranous bracts below the cluster of flowers, and the flowers have 6 lance-shaped petal-like tepals that are white or pinkish with green midveins. The ovary does not have a conspicuous crown.

Diagnostic Characteristics

The only other onion in northwest Montana that is usually less than 15 cm tall with only 2 leaves is A. TEXTILE, which has 3 bracts below the flower cluster and bulb coats that are very fibrous, resembling burlap.
