Bulbs without basal bulbels, 1-2 × 1-2.5 cm; inner coat cells obscure, regular or nearly so. Leaves usually 3-6; blade 1-6 mm wide, margins entire. Scape solitary, 20-60 cm. Umbel 25-60-flowered, producing capsules and seeds, bulbils almost unknown; spathe bracts 3, ovate to lanceolate. Flowers odorless, 5-8 mm; tepals spreading, lavender-pink, rarely white, thin; pedicel linear, ± stout, becoming subequal, 15-20 mm. 2n = 14, 28.

Flowering May--Jul. Generally in calcareous soils; 100--600 m; Ark., Ill., Kans., Mo., Nebr., Okla., S. Dak.

Perennial herb with one to four or more bulbs flowering stem 20 cm - 0.6 m tall

Leaves: usually three to six, arising from lower half of stem, 15 - 40 cm long, 2 - 7 mm wide, flat, grass-like.

Inflorescence: an upright, dome-shaped umbel of 25 - 60 flowers raised on a stout stalk and subtended by two to three bracts.

Flowers: on long stalks, usually lavender, rarely white, 5 - 8 mm wide, bell- to star-shaped, with six tepals that wither when the plant is in fruit. Stamens six, upright.

Fruit: a short, three-lobed capsule.

Bulbs: often clustered, without basal bulbils (little bulbs), up to 2.5 cm tall, somewhat oval or egg-shaped, and encased in a brown, fibrous, netlike coating. Bulbs have a strong onion-like odor.

Similar species: The fibrous netlike coating of the underground bulbs and the lavender flowers help distinguish Allium canadense var. lavandulare from other similar-looking Allium.

Flowering: June

Habitat and ecology: Introduced from south of the Chicago Region. Very rare in the Chicago Region. Has been found in dry gravelly soil and on a limestone barren.

Occurence in the Chicago region: non-native

Etymology: Allium comes from the Latin word for garlic. Canadense refers to Canada, but is also used in reference to North America (a result of early French influence).
