Climbing Cactus
Overview
Epiphyllum phyllanthus is a striking epiphytic succulent belonging to the family Cactaceae 1. Commonly known as the climbing cactus, this species is highly valued among collectors for its flat, leaf-like photosynthetic stems and nocturnal, tubular flowers.
Taxonomy and Naming
Originally described by Carl Linnaeus as Cactus phyllanthus, it was subsequently placed in the genus Epiphyllum 1. The generic name translates from Greek as 'upon the leaf', reflecting the peculiar way the floral tubes emerge from the margins of the leaf-like branches (cladodes).
Distribution and Habitat
This species enjoys a vast native range spanning from southern Mexico and the Caribbean through Central America down to tropical South America, including Brazil and Suriname 2. It thrives in seasonally dry tropical forests, growing non-parasitically on tree branches.
Appearance
The plant features elongated, flat, and thin green stems with wavy or scalloped margins. Spines are practically absent in mature specimens. Its elegant white or cream flowers open at night, emitting a sweet fragrance to attract nocturnal pollinators, followed by bright pinkish-red fruits.
Cultivation and Care
Unlike desert cacti, this forest epiphyte requires bright, indirect light and moderate to high humidity. The growing medium must be highly porous yet organic, kept lightly moist during the growing season and drier in the winter.
Common Cultivated Errors
Overwatering in heavy, compacted soil leads rapidly to root rot. Conversely, keeping the plant in bone-dry conditions under direct, scorching sunlight causes severe sunburn and stem shriveling.

Watering
6-14 Days
Water thoroughly once the top inch of soil is dry. Reduce watering in winter.
Soil
Lightweight, organic-rich, well-draining epiphytic potting mix (orchid bark, perlite, and peat mix).
Thrives in a chunky, well-draining mix containing peat, perlite, and orchid bark.
Safety
Pet Friendly
Non-toxic to cats, dogs, and humans. Safe for household cultivation.
Difficulty
Easy
Very easy to care for when provided with adequate humidity and aerated soil.
Native Habitat
Caribbean, Mexico, Central and South America
Naturally distributed across seasonally dry tropical biomes, extending from Southern Mexico through the Caribbean islands down to Brazil, growing as an epiphyte on host trees.
Frequently Asked Questions
How often should I water Epiphyllum phyllanthus?
During summer, water when the top layer of soil dries out (about every 5-7 days). In winter, reduce the frequency to once every 14 days.
Is this plant toxic to pets?
No, *Epiphyllum phyllanthus* is completely non-toxic and safe for both cats and dogs.
How can I encourage it to bloom?
During winter, keep the plant in a cool room (12-15°C) and reduce watering. This winter rest triggers bud development in spring.
What kind of soil mix should I use?
Avoid standard cactus soil; instead, use an airy, well-draining epiphytic mix containing peat, plenty of perlite, and orchid bark.
Should it receive direct sunlight?
No, harsh direct sunlight can burn its leaf-like stems. Bright, filtered, or indirect light is ideal.
When and how do the flowers bloom?
The flowers typically open at night during summer. They are long-tubed, white, highly fragrant, and close by morning.
Why are the stems of my plant shriveling?
Shriveling is usually caused by severe underwatering or root rot preventing water uptake. Check the moisture level of the roots.
How fast does it grow?
With adequate humidity, warmth, and nutrients, it is a moderate-to-fast grower, producing active new shoots during spring and summer.
When should I repot the plant?
Do not repot unless the plant is completely root-bound. Typically, repotting every 2-3 years in spring is sufficient.
Does it require pruning?
It is not mandatory, but you can prune overly long stems in late spring to shape the plant or propagate new cuttings.
