Allium tricoccum is a bulbous perennial flowering plant in the amaryllis family Amaryllidaceae. It is a North American species of wild onion or garlic found in eastern North America. Many of the common English names for this plant are also used for other Allium species, particularly the similar Allium ursinum, which is native to Eurasia. An edible plant, Allium tricoccum is used in a variety of North American and indigenous cuisines, and has also been used by Native Americans in traditional medicine. A French rendering (chicagou) of a Native American name for this plant is the namesake of the American city of Chicago. Allium tricoccum is a perennial growing from an ovoid-conical shaped bulb that is 2–6 cm (1–2 in) long. Plants typically produce a cluster of 2–6 bulbs that give rise to broad, flat, smooth, light green leaves, that are 20–30 cm (8–12 in) long including the narrow petioles, often with deep purple or burgundy tints on the lower stems. The bulbs are white and surrounded by brownish to grayish sheathing. Each cluster of bulbs gives rise to one flowering stem. The flowers are arranged into an umbel that has an erect scape that is typically 10–40 cm (4–16 in) long. The inflorescence has two ovate bracts that enclose the flowers before they open and fall away at anthesis. The flowering stem is persistent after fruiting. The flowering most commonly occurs after the leaves have died back, unlike the similar Allium ursinum, in which leaves and flowers can be seen at the same time. Ramps grow in close groups strongly rooted just beneath the surface of the soil. Flowering occurs in June or July into August. The flowers have white, cream or yellowish tepals which are 4–7 mm (1⁄8–1⁄4 in) long. The stamens are about as tall as the tepals and the filaments of the stamens have widened bases and are inserted on the corolla. After flowering and fertilization green fruits are produced that are three-lobed and open by way of three valves. The seeds are round, black, and shiny.
