About Lemmon's Onion (Allium lemmonii) Allium lemmonii is a species of wild onion known by the common name Lemmon's onion. It is native to the western United States, particularly higher-elevation areas in the Great Basin. Lemmon's onion grows from a bulb one and a half to two centimeters wide and has a short, flattened stem which is thin along the edges. Atop the stem is an flower cluster of 10 to 40 flowers which may be white to pink. The stamens may be light or dark in color. The ovary has a distinctive ridged mound shape in which all of the ovary parts appear melded together. This is a common plant in its native range. It favors dry clay soils.
