Allium stellatum (autumn onion, prairie onion[1]) is a North American species of wild onion native to central Canada and the central United States from Ontario and Saskatchewan south to Tennessee and Texas.[2][3]

Allium stellatum grows in rocky, sandy soil.[4] It is a perennial forming a bulb. The scape is up to 1–2 feet (30–60 cm) tall with tufts of leaves,[5] which are thick, hard, and rounded on the back.[6] The leaves die back as the umbel of pink to purple flowers[5] forms in early August.[6] The bulbs are strongly flavored but edible.[5]

The species name stellatum is botanical Latin for "starry", and refers to the umbels. This species was described for science by John Bellenden Ker Gawler in 1813.[7][8]
