Wild leek, Allium tricoccum.

Wild leek (Allium tricoccum) is one of the better-tasting species of wild onion found in Canada, but because it has a low level of toxicity, it should be eaten in small quantities. The leaves, bulbs and bulblets are edible. The fruits are three-lobed capsules with one, black seed per lobe. Native people have used juice from the crushed bulbs to treat insect stings. Wild leek grows in rich woods and moist ground from southern Manitoba to Nova Scotia and New Brunswick. It is becoming rare in some localities because of over-harvesting.
