Selenicereus anthonyanus “Ric-Rac” Cactus: Complete Care and Growing Guide
Also known as the Fishbone Cactus or Rick Rack Cactus, Selenicereus anthonyanus is a tropical epiphytic cactus that brings bold, sculptural charm to any space. Its zigzagged, flattened stems give it an almost artistic look, making it a favorite among plant lovers and collectors.
Native to the humid forests of Mexico, this cactus grows on trees and rocks, thriving in dappled light and warm conditions. But what truly sets it apart is its breathtaking night-blooming flowers. When mature, it produces large, fragrant blooms in creamy white with soft pink edges—sometimes up to 6 inches wide. These flowers open only at night, creating a magical display you’ll never forget.
