Allium acuminatum, also known as the tapertip onion or Hooker's onion, a species in the genus Allium and is native to the Western United States and Canada. It has been reported from every state west of the Rocky Mountains, plus British Columbia.[2][3]

Allium acuminatum produces bulbs that are spherical, less than 2 cm across and smelling like onions.[4] Scape is up to 40 cm tall, wearing an umbel of as many as 40 flowers. The flowers are pink to purple with yellow anthers.[2][5][6][7][8][9][10]

The onions were eaten by first peoples in southern British Columbia. They were harvested in either early spring or late fall and usually cooked in pits.[4] Both the bulb and the flowering stalk are edible; however, in the culinary arts, the stalk possesses a more pleasant flavour.[4]
