Brief Summary

    Allium victorialis: Brief Summary
    provided by wikipedia

    Allium victorialis, commonly known as victory onion, Alpine leek, and Alpine broad-leaf allium is a broad-leaved Eurasian species of wild onion. It is a perennial of the Amaryllis family that occurs widely in mountainous regions of Europe and parts of Asia (Caucasus and Himalayas).

    Some authors consider certain East Asian and Alaskan populations as constituting subspecies platyphyllum within the species Allium victorialis. Recent sources recognize this group as a distinct species, called Allium ochotense.

    A very distinct species. Found in the northern mountainous regions of our area. The plant is used for food in USSR and is said to have anti-scorbutic properties.

    Allium victorialis is found in North America only on Attu Island, where it is reported to be native, and on Unalaska Island, where it is reported to be introduced from Attu Island. Within this species, various subspecies and varieties have been described, but, as circumscribed, they are not clearly distinct. The North American plants have been known as subsp. platyphyllum, but until the variation within this widespread species can be worked out along natural lines, recognition of infraspecific taxa seems pointless.
