Wild Agave potatorum (Tobalá) on the road to Mixteca. Habitat 4000–7500 feet of elevation. A highly variable species, Agave potatorum may soon become more than one species, according to author and agave expert, Greg Starr (Agaves: Living Sculptures for Landscapes and Containers). Takes about 15 years to mature. If you ever have the opportunity, this (rather long) drive is chock-a-block with a variety of agave species. Have your camera ready and be prepared to stop. A lot.
