Allium hoffmanii is a species of wild onion known by the common name beegum onion.[2][3][4] It is native to northern California, where it grows in the serpentine soils of the local mountain ranges in Siskiyou, Humboldt, Trinity, Shasta, and Tehama Counties.[5][6]

This onion grows a short stem up to about 10 centimeters tall from a brown or reddish bulb one or two centimeters long. There is generally a single leaf which may be longer than the stem. The inflorescence is packed with up to 40 flowers, each about a centimeter long and pink or purple in color with greenish veining. The protruding stamens are bumpy at their bases and have purple anthers at the tips.[7][8]
