Orchid Cactus Facts

Overview

The orchid cactus is stunning when it blooms and makes an undemanding houseplant. Unlike desert cacti, it lacks sharp thorns, although it does have tiny hair-like spines at the joints.

Names

The orchid cactus gets its name from its spectacular blooms, which resemble the flowers of some orchids. Because orchid cacti belong the the epiphyllum species, some growers call them "epis" for short.

Native Habitat

Orchid cacti are native to Central and South American rain forests, where they grow in the crowns of tall trees. They take nourishment from their environment, not other plants.

Description

Though it is a true cactus, the orchid cactus looks quite different from arid climate cacti. It has flat, fleshy, deeply toothed stems that adopt a trailing growth habit. The flowers can be 6 inches long, and come in many colors.

Flowering

Day-flowering orchid cacti generally bloom from April through June. Night-flowering types can be fragrant and bloom in late summer and early fall. Plants flower when they are about 2 years old.

Care

Rain forest cacti require humidity and moisture, but should never be allowed to become waterlogged. They prefer bright but filtered light and will sunburn if they receive too much sun.
