Selenicereus anthonyanus is a cactus species native to southern Mexico. It is grown as an ornamental because of its nocturnal flowers and leaf-like stems. Common names are fishbone cactus, rick rack cactus, zig-zag cactus and St. Anthony's rik-rak.
Selenicereus anthonyanus is an easy, fast growing epiphyte plant. It is most frequently cultivated as a house plant (in pots and hanging baskets). It rarely planted outdoors in tropical countries, where climbs trees in a semi-naturalized state. In nature it climbs into trees. Older plants in the greenhouse buds freely. It can be trained to climb a trellis, but looks best in a hanging basket from whence the lightning-shaped leaves will dangle 60- 90 cm over the edge. Because the flowers are so quickly spent, this epiphyte is mainly only grown for the strange leaves which lend it the common name Ric-Rac Cactus, or occasionally Zig-Zag or Fishbone Cactus.
