The crested euphorbia is a freak of nature, because it’s technically two plants that have been joined together. Most of the time, a Euphorbia lactea is grafted onto the stem of another succulent, like a Euphorbia neriifolia. This unusual procedure creates a strangely pretty plant with a unique fan shape. Since Crested euphorbia is drought-tolerant and requires little water, home maintenance is relatively easy—as long as you don’t mind caring for a succulent that has undergone a surgical procedure!
