Subspecies, varieties, forms and cultivars of plants belonging to the Agave utahensis group

Agave utahensis is variable over its range and comprises two subspecies, subsp. kaibabensis and subsp. utahensis, the latter of which comprising at least 2 varieties, var. nevadensis and var. eborispina. These varieties are now regarded by some botanists as mere ecotypes or geographical forms, so now they are all synonymized with Agave utahensis, but still considered distinct by collectors for their peculiar traits.

  • Agave utahensis Engelm. in S.Watson: (subsp. utahensis)
  • Agave utahensis var. eborispina (Hester) Breitung: has the longest spines of any, often cream or white in colour. Forms small clumps with only a few stems. Distribution: Nopah Mountains
  • Agave utahensis subs. kaibabensis (McKelvey) Gentry: is an attractive solitary form with bright green leaves and grey-white teeth.
  • Agave utahensis var. nevadensis Engelm. ex Greenm. & Roush: smaller than type, has broader, bluish green leaves with strong marginal teeth. It suckers slowly eventually forming a large matt of spines where you can't tell which leaf belongs to which plant.
