Agave utahensis is a species of agave known by the common name Utah agave. There are two recognized varieties in California, both of which are rare. 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. It is found in the high desert mountains of Inyo and San Bernardino Counties. This is a rosette-shaped agave having blue-green sharp-spiked leaves. The raceme flower cluster is very tall, reaching a maximum of four meters. It is generally yellow or yellow-green with bulbous yellow flowers. The fruits are capsules 1 to 3 centimeters long and containing black seed. The plant was used for food and fiber by local Native American peoples such as the Havasupai.
