What is Epiphyllum?

Much of the answer lies in the word. Their primarily epiphytic nature is indicated by the beginning of the word. These plants are native to the tropical Americas and range from Mexico to Central America and even into the Caribbean.

Orchid cactus have flat, fleshy stems with serrated edges. Most have a trailing appearance but since there are hundreds of cultivars, other habits can be found as well. In warm climates, these cacti need a bit of shade during the hottest part of the year. Otherwise, they need temperatures between 45 and 70 degrees Fahrenheit (7 to 21 C.). All Epiphyllum varieties are heat lovers and cannot tolerate any freezing temperatures.

There are both day flowering and night blooming species. Epiphyllum varieties of flower colors range from purples, to pink hues, oranges, reds and even white. In their native range, they are tree dwelling plants whose roots take nutrients and moisture from the air. As such, they have very low nutrient needs and their primary requirement is humidity.

Growing Cactus Orchid Plants

Epiphyllum plants require humid conditions that mimic their tropical rainforest home. Mist plants frequently, especially in hot conditions.

Use a light, well-draining, humus rich potting mixture. Cactus orchids prefer to be pot bound but, when necessary, repot them do after flowering.

Feed the plant with low nitrogen in late winter/early spring and again in mid fall. Suspend fertilizing in the winter months and reduce watering by half.

During the growing season, keep containers evenly moist, especially during flowering. If you want to make more of these elegant plants, simply remove a length of stem, allow it to callus over for a couple of weeks and then insert the stem in moistened sand. Keep the cutting in moderate light and slightly on the dry side until rooting occurs. This is the quickest, easiest way to get more of these brightly colored plants.
