About Fishbone cactus
Selenicereus anthonyanus, commonly known as Fishbone Cactus or Ric Rac Cactus, is an epiphytic cactus with flat, zigzag stems resembling a fish skeleton. Its spectacular, large, fragrant white flowers open at night, adding an exotic touch. It's perfect for hanging baskets or high shelves where its stems can cascade freely.
Native range
Mexico (Chiapas, Oaxaca, Veracruz)
Care tips
It prefers bright, indirect light; direct sun can scorch its stems. Water thoroughly when the substrate is completely dry, reducing frequency in winter to prevent root rot. Use a well-draining substrate, specific for cacti or epiphytes. Avoid overwatering, as it is the most common cause of problems for this species.
