Although you can’t tell from the photos here, this cycad species can get quite tall. I’ve seen photos from habitat with what appears to be over 20 feet of trunk. Dioon spinulosum is native to tropical areas in Mexico where it grows in limestone forests. Trunks don’t get overly thick, typically 12 to 14 inches thick. With age, this can be more. Leaves are green and mildly armed. Leaf length is about six feet. My preference is to grow this species in filtered light. Cold tolerance is into the mid twenties F. Be aware, to get a foot or two of trunk can take a few decades. At the nursery we usually have a good selection of this species from small to large. Photos below shown some nursery plants as well as plants in gardens.
