Out of all the different species I have planted outside in a sand-gravel raised desert bed, this agave has handled the Arkansas climate the best....Grows fast, even put out offsets during fall and winter (when it gets more than half-day shade), handles record amounts of rain over the last year with absolutely no issues.

Very attractive ghostly agave with nearly white leaves, and prominent, black-brown lateral and terminal spines. This is also a slow suckerer, making it a useful and manageable landscape agave. Very striking in a setting with darker colored plants. Similar looking to Agave parryi varieties.
