Stenocereus griseus, also known as the Mexican organ pipe, dagger cactus, pitaya, and pitayo de mayo, is a species of cactus native to Mexico. It can grow to be 30 feet tall! Its fruit is edible to humans and is considered yummy. It is planted as an ornamental and as a living fence in warm regions. When used as a fence, it can be impervious to animals due to its spiny nature. For best results give your cactus 3-4 hours of direct sun a day. The more the better. You can't give it enough. Always allow your cactus to dry completely and stay dry for a few days between waterings.
