Agave utahensis var. eborispina (Ivory-spined Agave) - A small clump forming agave to 8 to 12 inches tall by 1 foot wide with 4 to 8 inch long leaves that have heavily toothed leaf margins and stout 1 1/2 inch long ivory-colored terminal spines. When plants mature in habitat they flower in late winter with 6 to 12 foot tall spikes. Plant in full sun in a well-drained soil and irrigate little if at all. This plant grows on dry limestone slopes from 3000 - 5000 feet elevation in SE California, Nevada, and Utah. Plants in California are limited to the Nopah Range in Inyo County - our first crops of this species were grown from seed collected by Brian Kemble from the foothills of Mt. Charleston (NW of Las Vegas, NV). Our more recent crops came to us from seed Tony Krock collected at Lee Canyon in the same area and from Hancock Summit about 90 miles north of Las Vegas at around 5592 feet in elevation. The subspecies Agave utahensis var. eborispina has most recently been combined with var. nevadensis as Agave utahensis var. nevadensis. It has a California Rare Plant Rank:1B.3 meaning nevadensis is rare, threatened, or endangered in California and elsewhere and State Rank of S1.3 meaning that it is critically Imperiled. 

This information about Agave utahensis var. eborispina displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
