About Nevada Agave (Agave utahensis var. nevadensis) Nevada Agave (Agave utahensis var. nevadensis) is a rare native perennial herb or shrub in the Agavaceae family. It is one of two recognized varieties of Agave utahensis, both of which are rare. Var. nevadensis is restricted to the desert mountains of eastern San Bernardino County at elevations from 3,000-5,200 feet. Due to its limited distribution, it is included on CNPS list 4.2. Agave utahensis is smaller, occurs farther north, at higher elevations, and is more cold tolerant than the other two native agaves in California. Like other agaves, it is armed with formidable spines and flowers after many years of growth, then the plant dies but clonal pups remain. The inflorescence is 5-13 ft. tall. The flowers are yellow-green and the fruit is a dry capsule.
