About Allium nevadense S.Watson
Allium nevadense, commonly called the Nevada onion, is a species of wild onion. It is native to the western United States, where it grows in sand and rocky soil at elevations between 1400 and 1700 m. This species is widespread across Utah, Nevada, and southern Idaho. It has also been recorded in southeastern California (Inyo and San Bernardino Counties), northwestern Arizona (Mohave and Cochise Counties), western and central Colorado (Moffat, Garfield, Mesa, and Boulder Counties), and eastern Oregon (Harney and Malheur Counties). Nevada onion grows from a brown or gray bulb 1 to 1.5 centimeters wide, which often has one or two small attached daughter bulblets. If the bulb sits more than a few inches below the ground surface, the stem will appear shorter than typical. The top of the stem holds an umbel that can have up to 25 flowers. Its tepals are white or pink-streaked, with darker midveins; the anthers are purple, and the pollen is yellow.
