[8] Allium canadense has an edible bulb covered with a dense skin of brown fibers.

[11][failed verification] The narrow, grass-like leaves originate near the base of the stem, which is topped by a dome-like cluster of star-shaped, pink or white flowers.

[11] When present, the flowers are hermaphroditic (both male and female organs) and are pollinated by American bees (not honeybees) and other insects.

[18] Five varieties of the species are widely recognized:[5][11] The Canada onion is cultivated as a vegetable in home gardens in Cuba,[b] scattered locally in the south to western parts of the island.

[22] Additionally, long term consumption of wild onion bulbs reduces iodine uptake by the thyroid gland.
