This is a large Dasylirion, colored similarly to D wheeleri, though the leaves are wider, less blue and more grey, and do not tend to be twisted at all (not sure why called blue twister)... also leaves don't end in the same dried tassels that D wheeleri leaves do. Also, about 2-3x the size of D wheeleri. Viciously sharp teeth along leaf edges, similar to wheeleri. Native of Mexico
