Euphorbia Anoplia is a unique cactus plant with an interesting pattern and structure. Will grow up to a foot tall and form clusters at the base of the mother plant. The pattern or markings on this cactus are striped that develop between the ridges of the cactus, making it look like zippers. The best thing about this cactus is that it has very little sharp spines to worry about. Euphorbia varieties contain a white, latex sap that can cause skin irritation or allergic reaction.
