Epiphyllum anguliger

Botanical Name — Epiphyllum anguliger

Common Name — Ric-Rac Cactus or Fishbone Cactus

Plant Family — Cactaceae

Background

Epiphyllum anguliger is a night blooming epiphytic cactus native to evergreen forests in Mexico, where it grows clinging to the limbs and trunks of trees. An oddity in the cactus family, it is native to rainforest conditions, meaning it loves high humidity and more frequent watering. Keep an eye out for showy, fragrant, night-blooming flowers in the fall which only last one night so be sure to stay home for the show.

Growth Requirements

Sun

Epiphyllum anguliger love a couple hours of direct sunlight, but prefer to stay in partial shade for most of the day. The diffused light of a screen door or sheer curtain will imitate the dappled sunlight of a rainforest canopy.
Make sure the Ric-Rac has protection from the sun during the hottest hours of the day. They are prone to burn or bleach if grown in too much direct sun.

Temperature/ Humidity

Epiphyllum anguliger are tropical plants, meaning they thrive in temperatures between 65 to 80 ºF. They should always be kept above 55 ºF.
Though they like humidity, they can tolerate and thrive in a normal home environment (most of our homes are low in humidity, especially in the winter). That being said, it can benefit from misting with tepid water or a humidifier.

Water

Native to the rainforest, the Ric-Rac likes more water than other members of the cactus family. Water when the top layer of soil – about an inch down – is dry. Epiphyllum anguliger’s succulent leaves retain plenty of moisture so be sure to let that soil dry out.
In the winter, when these plants are not actively growing, ease up on watering even more. Reduce the frequency of watering to about half of what you would provide in the summer.

Soil/Roots

Give Epiphyllum anguliger a gritty, well drained soil. A good cacti or succulent mix would suffice. Alternatively, a typical potting soil amended with sand or fine pumice up to 25% will accomplish the aeration and drainage these plants need to thrive.

Flowering

Dramatic flowers up to 8 inches in length may bloom in late summer or fall. They have a sweet scent, and only bloom at night.
The blooms only last one night, by morning they will be wilted.
Flowers can be white, pink and fuschia. There are many hybrids of this plant on the market with incredible bloom colors.

Fertilization

Fertilization is during spring and summer up until flowers stop blooming in the fall.
Apply a tomato or cactus fertilizer every two weeks. Do not fertilize in late fall or winter.

Propagation

These plants can be easily propagated by stem or leaf cuttings. They will push out aerial roots from the underside of the leaves, which is how they attach onto surfaces like trees in their natural habitat.

Health

Diseases

Due to its delicate root system, Epiphyllum anguliger is susceptible to root rot. Make sure you let soil dry out completely between waterings.
Fungal leaf rot may occur during spring rains, creating brown spotting and scarring on the stems. Remove infected limbs with clippers.
Scale, mealybugs, and aphids can be common pests. Remove pests with a cotton ball or q-tip soaked in rubbing alcohol, or treat the plant with diluted neem oil. Prune away unhealthy leaves or stems.
