Agave potatorum or the Butterfly Agave is a beautifully symetrical, smaller succulent that is very drought tolerant and therefore ideal for xeriscape gardens.
It forms a neat rosette of fleshy blue to grey leaves that are dangerously spiny - beware.
When the plant is fully matured it produces a single flower spike topped wit light green flowers tinged with red.
The plant will usually die back after flowering.
One of the great and graphically impactful Agaves that make it a must for modern garden designs.
