As someone who enjoys collecting unique plants, I am constantly searching for green companions that bring something special to my indoor garden. Plants with unusual growth patterns and impressive flowers always catch my attention. Epiphytic plants are among my favorites because they are full of surprises. Unlike terrestrial plants that grow in soil, epiphytes naturally grow on other plants without taking nutrients from their hosts.

Many epiphytes, including staghorn ferns, certain orchids, air plants, bromeliads, and epiphyllums, are fascinating species worth exploring. In their natural habitats, these plants often grow in the organic debris collected on tree branches. This creates a small ecosystem where birds, insects, reptiles, and other creatures interact, providing nutrients and shelter for one another.

Two members of the Epiphyllum group that have recently captured my interest are Epiphyllum oxypetalum and Epiphyllum anguliger. Among the many flowering epiphyllum species found in nature, these two varieties and their hybrids are among the most popular choices for growing indoors.

About Epiphyllum Oxypetalum

Epiphyllum oxypetalum is commonly called Dutchman’s Pipe Cactus, Queen of the Night, Lady of the Night, Orchid Cactus, or Night-Blooming Cereus. However, these common names can sometimes create confusion. Despite the name “orchid cactus,” this plant is not an orchid, nor is it a true cereus or Dutchman’s pipe plant. It is actually a shade-loving cactus.

Many plants share similar common names because they produce flowers with comparable appearances or bloom at night, but their growing requirements can be completely different. Botanical names provide a more accurate and universal way to identify plants, while relying only on common names can sometimes lead to incorrect identification and improper care.

The Amazing Night Flowers of Epiphyllum

The most remarkable feature of Epiphyllum plants, aside from their large, dramatic foliage, is their incredible nighttime flowering display. They produce huge, exotic, and sweetly scented flowers that open during the night and fade by morning.

Their breathtaking blooms usually appear between midnight and sunrise, leaving behind wilted flowers once daylight arrives. Although some people believe Epiphyllum oxypetalum only flowers once each year, this is not always true. Under suitable conditions, a healthy plant may produce several rounds of nighttime blossoms over a period of weeks.

Some other rare epiphyllum species and similar night-flowering cacti may only bloom for a single night each year, making their displays even more special.

About Epiphyllum Anguliger

Epiphyllum anguliger is often known as the Fishbone Cactus, Zig Zag Cactus, or Ric Rac Cactus. It is one of the most distinctive-looking houseplants because of its unusual flat leaves with deep zig-zag edges.

The unique leaf shape creates a beautiful silhouette, especially when the plant is placed near a window or allowed to trail from a hanging container. Compared with Epiphyllum oxypetalum, this species is generally more reluctant to flower and may require additional encouragement.

To stimulate blooming, it can benefit from a fertilizer higher in potassium and phosphorus, along with a cooler resting period during late winter.

Natural Habitat and Light Requirements

Both Epiphyllum oxypetalum and Epiphyllum anguliger originate from tropical forests and jungle regions of Mexico, Central America, and South America. In their native environment, they are pollinated by nighttime-active creatures such as nectar-feeding bats and insects.

Because these plants naturally grow beneath forest canopies, they should not be exposed to harsh, direct sunlight. Indoors, they perform best near an east-facing window with gentle morning light or in bright locations with filtered sunlight from south or west-facing windows.

Unlike desert cacti that prefer dry soil and intense sun, epiphytic cacti enjoy more moisture and humidity. During their active growing season in spring and summer, they should receive thorough watering about once a week and should not be allowed to completely dry out.

Growing Epiphyllum Outdoors

During warm summer months, Epiphyllum plants can be moved outdoors where they can enjoy natural humidity and filtered light. Hanging them from a tree branch is an excellent way to recreate their natural forest environment.

Outdoor placement also makes it easier to observe the development of their long, curved flower buds. Watching these buds grow and preparing to stay awake for their midnight blooming event can be one of the most rewarding experiences of growing these plants.

Potting and Root Care

Epiphyllum plants prefer being slightly root-bound, so they should not be moved into oversized containers too quickly. When repotting, increase the pot size gradually by only a few inches at a time.

A slightly crowded root system can actually encourage flowering. However, moving the plant into a larger pot may stimulate rapid growth, and these plants can eventually become surprisingly large. Some mature Epiphyllum oxypetalum plants can develop a spread of several feet.

Always choose containers with drainage holes and avoid allowing the roots to sit in standing water. A cactus potting mix works well, or regular potting soil can be combined with orchid bark to improve drainage.

Fertilizing and Encouraging Blooms

Epiphyllum plants benefit from fertilizers that are low in nitrogen and higher in potassium and phosphorus. Products containing seaweed or fish emulsion can also support healthy growth.

If a mature plant between four and seven years old is not producing flowers, a short cooling period may help trigger blooming. Place the plant in a bright but unheated area during late winter for about two to three weeks, making sure temperatures stay above 40°F.

Propagating Epiphyllum

Epiphyllum plants are easy to reproduce through leaf cuttings. Simply allow a cutting to dry for several days until the cut surface forms a protective layer.

After the cut end has hardened, dip it into rooting hormone or rooting gel and place it into loose, slightly moist potting soil. Small root-like structures may appear along the leaf surface; these structures help the plant attach itself to tree branches in its natural habitat.

Enjoying These Unique Plants

Epiphyllum cacti are wonderful choices for plant lovers who enjoy unusual shapes, dramatic flowers, and fascinating growth habits. Their combination of tropical origins, easy propagation, and unforgettable nighttime blooms makes them truly special additions to any collection.

With the right light, moisture, and care, these remarkable plants can reward growers with years of beautiful foliage and spectacular flowers.
