Gray Ghost Organ Pipe Cactus
This large, shrubby columnar cactus becomes tall dark green with age but is a nice powdery blue gray when young. They will nocturnally produce small white flowers that have a pink tinge and following the flowers are very large edible fruits about the size of a small apple that will change color from yellow, orange-green to a purple. This cactus is great for a native landscape needing full sun, little water, and no fertilizer. They also require little to no pruning making them a worry free addition. They will grow to be around 15-20ft tall with a 10ft spread.
