Crenate Orchid Cactus (Epiphyllum crenatum): An Epiphytic Beauty with Fragrant Nocturnal Blooms

The Crenate Orchid Cactus is a classic epiphytic cactus with long, flat, scalloped (crenate) stems that cascade gracefully. In spring or early summer, it produces huge, fragrant, white flowers up to 7 inches across that open at night and fade by midday. Native to Central American cloud forests, it grows on trees or rocks, making it ideal for hanging baskets or mounted plaques where its pendulous habit can be appreciated.

Culture Tips

Bright, filtered light; avoid hot afternoon sun. Use a rich, well-draining epiphytic mix (orchid bark, peat, perlite). Keep evenly moist during growth, slightly drier in winter. High humidity appreciated. Minimum 50°F (10°C). Fertilize with balanced orchid fertilizer during active growth.
