Coral Cactus, or also known as Euphorbia lactea Cristata, is an incredibly unique succulent that looks like a large coral reef with a green thick stem and crinkled cabbage-like leaves. Coral Cactus is not really a cactus but is actually two succulents joined together to create one beautiful coral-looking plant, which has a lot of names, like candelabra plant, the crested candelabra plant, crested euphorbia, and crested elkhorn.
