Anthony's Rick-Rack, Zig-Zag Cactus, Fishbone Orchid Cactus. It is nightblooming and its flowers last only a single night in spring. 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. It can be grown either in orchid substrate, or in regular cactus potting soil with a bit of humus added. In the wild it attaches itself to trees, clinging by little aerial root filaments along the zigzagging succulent leaves, but is adaptable to terrestrial habits. It loves strong yet indirect lighting. It does not need a lot of water and should be permitted to dry out entirely between waterings.
