Allium hoffmanii (Beegum onion) is a native California herb in the Alliaceae family, recognized by warty stamens and single wide leaf.

Beegum onion is a rare (CNPS 4.3) California native perennial found in southern Klamath Ranges and northern North Coast Ranges Highlands in serpentine outcrops at elevations of 1,100 to 1,800 meters. Flowering from June to July, this plant produces pink to purple flowers in clusters of 10 to 40 blooms, with distinctive lance-linear perianth parts and prominent green midveins. Growing with short stems 5 to 10 centimeters tall, it emerges from a small ovoid bulb 15 to 25 millimeters in size. Its single leaf is widely channeled and grows one to two times the length of the stem. The flower's stamens are uniquely bumpy or warty near the base, creating an intriguing textural detail.
