Hylocereus undatus is a red skinned climbing cactus that has received world-wide recognition as an ornamental plant for its large, scented, night-blooming flowers. It produces fruit of 0.5 kg or more and has a light melon-like taste. The colour of the skin is a beautiful bright red, with translucent white flesh and tiny black seeds. The species is easily recognisable by the triangular cross-section of its stem and minimal spines. This species pollinates very well with Hylocereus polyrhizus.
