About Epiphyllum thomasianum
Epiphyllum thomasianum, commonly known as Orchid Cactus, is an epiphytic cactus from the Cactaceae family, valued for its spectacular, large, and fragrant nocturnal flowers. Its flat, succulent stems, with serrated edges, hang gracefully, making it ideal for hanging baskets or as an indoor plant in a spot where its night-blooming flowers can be admired.
Native range
Mexico and Central America
Care tips
It prefers bright, indirect light, avoiding direct sun that can scorch its stems. Water moderately, allowing the substrate to dry out slightly between waterings, and reduce watering in winter. Use a well-draining substrate rich in organic matter, similar to that for orchids or bromeliads. A common mistake is overwatering, which can lead to root rot.
