Additional comments: If you're a small agave collector like me, you have to have this wonderful small agave in your garden or front yard landscape for all to see. It's totally people friendly.

The taxonomy of Sharkskin agave is confusing and somewhat disputed. Another name occassionally and incorrectly attributed to this wonderful hybrid is Agave 'Ruth Bancroft' from the Ruth Bancroft Garden in Walnut Creek, California. This name is confusing and apparently not supported by the Ruth Bancroft Garden staff who would rather have their similar looking Agave hybrid selection called 'Sharkskin Shoes' to differentiate their plants from those originating from the Huntington Botanic Garden.
