This species is from Texas and northern Mexico, where it tends to grow in the coastal mountains. Some consider it to be part of the Agave lophantha complex, but it appears to be significantly different to us. The leaves are green with a central yellow line and are lined with spines. We’ve grown this species outside in Tucson, where it has been undamaged at 15F. These plants are rooted offsets in 2-gallon pots.
