About Disocactus nelsonii
Disocactus nelsonii, commonly known as the orchid cactus, is an epiphytic cactus that produces flat, pendulous, deep green stems that can reach several meters in length. Its large, showy flowers, ranging from intense pink to purple, bloom along the edges of the stems, creating an impressive floral display in spring and early summer. It is ideal for hanging baskets or tall pots, where its stems can cascade freely, adding a tropical and exotic touch to any indoor or sheltered outdoor space.
Native range

Care tips
It requires bright but indirect light; direct sunlight can scorch its stems. Water moderately, allowing the substrate to dry slightly between waterings, and reduce frequency in winter. Use a well-draining and aerated substrate, specific for orchids or epiphytes, with good moisture retention. A common mistake is overwatering, which can lead to root rot and stem base decay.
