Allium nevadense (Nevada onion) is a native California herb in the Alliaceae family, recognized by unique coiled leaf tips and stalked bulblets.

Nevada onion is a rare (CNPS 2B.3) California native perennial found in the Desert Mountains in sandy or gravelly slopes at elevations of 1,300 to 1,700 meters. Flowering from April to June, this plant produces delicate white to pink flowers in small clusters with 5 to 25 blossoms, each flower 7 to 12 millimeters long. Growing with slender stems 5 to 15 centimeters tall, it emerges from a small ovoid bulb that produces 1 to 2 small bulblets at its base. Its single leaf is distinctively cylindrical and nearly twice the stem's length, with a tightly coiled tip that withers over time. The plant's bulb is characterized by intricate, transversely elongated cell patterns on its outer coating, creating a unique textural signature.
