Disocactus ackermannii: The Spectacular Orchid Cactus

The Strap-Leaf Epiphyllum

Disocactus ackermannii (syn. Epiphyllum ackermannii), known as Orchid Cactus or Strap Cactus, is a magnificent epiphytic cactus native to the cloud forests of Mexico and Guatemala. Its huge, brilliant red flowers and flattened, leaf-like stems make it a legendary flowering houseplant.

Taxonomic History

Epic Epiphytic Blooms

This epiphytic cactus has flattened, strap-like, scalloped stems 12-24 inches long that cascade gracefully. In spring, it produces enormous, funnel-shaped flowers 4-6 inches across in brilliant crimson to scarlet, with numerous petals and a central boss of yellow stamens. The flowers last several days each, opening sequentially for weeks of display.

Orchid Cactus thrives in bright, indirect light with a well-draining, humus-rich epiphytic mix. Keep evenly moist during growth; drier in winter. High humidity and good air circulation are essential. Minimum 50°F. Perfect for hanging baskets where the pendant stems and flowers display beautifully.

Legendary Houseplant

A Victorian parlor favorite that remains one of the most spectacular flowering cacti. The stems are spineless and architectural year-round. Easy to propagate from stem cuttings. Hybridizes readily with other epiphytic cacti, creating the vast Epiphyllum hybrid complex. A must-grow for cactus and succulent enthusiasts.
