Description
Peniocereus serpentinusSN|7249]]SN|7249]] is a fast-growing slender, shrubby columnar cactus that grows often in groups, erect at first sometimes climbing then leaning and sprawling all over and best tied to something so it wont fall and grow decumbent. It would be good for hanging baskets. This species is in need of taxonomic review as in Mexico it is recognized as a separate genus Nyctocereus; there is genetic evidence for this.
