Allium canadense, the Canada onion, Canadian garlic, wild garlic, meadow garlic and wild onion [4] is a perennial plant native to eastern North America from Texas to Florida to New Brunswick to Montana. The species is also cultivated in other regions as an ornamental and as a garden culinary herb.[5] The plant is also reportedly naturalized in Cuba.[6]

Description[edit]

Allium canadense has an edible bulb covered with a dense skin of brown fibers. The plant also has strong onion odor and taste. Crow garlic (Allium vineale) is similar, but it has a strong garlic taste.[7]

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. These flowers may be partially or entirely replaced by bulblets.[7] When present, the flowers are hermaphroditic (both male and female organs) and are pollinated by American bees (not honeybees) and other insects. It typically flowers in the spring and early summer, from May to June.[7][8][9][10][11][12][13][14]

Varieties[edit]

The bulblet-producing form is classified as A. canadense var. canadense.[7] It was once thought that the tree onion could be related to this plant,[15] but it is now known that the cultivated tree onion is a hybrid between the common onion (A. cepa) and Welsh onion (A. fistulosum), classified as A. × proliferum.[16]

Five varieties of the species are widely recognized:[3][7]

  • Allium canadense var. canadense - most pedicels replaced by bulbils, rarely producing fruits or seeds; most of the range of the species
  • Allium canadense var. ecristatum Ownbey tepals deep pink and rather thick; coastal plain of Texas
  • Allium canadense var. fraseri Ownbey - flowers white; Great Plains from Texas to Kansas
  • Allium canadense var. hyacinthoides (Bush) Ownbey - tepals pink, thin, flowers fragrant; northern Texas and southern Oklahoma
  • Allium canadense var. lavandulare (Bates) Ownbey & Aase - flowers lavender, not fragrant; northern Arkansas to South Dakota
  • Allium canadense var. mobilense (Regel) Ownbey - flowers lilac, pedicels thread-like; southeastern US

Uses[edit]

The Canada onion is cultivated as a vegetable in home gardens in Cuba, scattered locally in the south to western parts of the island. It was formerly collected from the wild to be eaten by Native Americans and by European settlers.[17] People in the Western Cherokee Nation continue the tradition of picking and cooking wild onions in early spring.[18] Various Native American tribes also used the plant for other purposes: for example, rubbing the plant on the body for protection from insect, lizard, scorpion, and tarantula bites.[19]

This plant can cause gastroenteritis in young children who ingest parts of this plant. Chronic ingestion of the bulbs reduces iodine uptake by the thyroid gland, which can lead to problems. No specific treatment is suggested other than to prevent dehydration (Lampe and McCann 1985). Livestock have also been poisoned by ingesting wild onions, and some have died (Pipal 1918). Horses have developed hemolytic anemia from ingesting wild onion leaves (Scoggan 1989).[20]
