Additional comments: This is a fantastic small agave for those smaller 'up close and personal' landscape spaces. It is used in the landscape much the same as A. geminiflora or A. macroacantha, but with different textural and color characteristics. Its leaves are a source of strong fibers (the word 'ocahui' is literally translated to mean 'cord'). The leaves contain saponin smilagenin which can be used as a detergent.

There are two varietal selection of Agave ocahui:

  1. A. ocahui var. ocahui has stiff, smooth, dark green leaves that are only 10 to 20 inches long, with a dehiscent white to brown border, but no marginal teeth, and a weak, flexible spine. The rosette generally remains solitary without basal offshoots.
  2. A. ocahui var. longifolia has stiff smooth leaves that are up to 3 feet long and 1 inch wide without marginal teeth.

Here's a cool Agave hybrid.....it's Agave ocahui X Agave attenuata 'Blue Glow'.
