Lemmon's onion grows from a bulb one and a half to two centimeters wide and has a short, flattened stem up to 20 cm tall, which is thin along the edges. Atop the stem is an inflorescence of 10 to 40 bell-shaped flowers, which may be white to pink. The stamens may be purple or yellow; pollen is yellow. 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.[4][7][8][9]
