Epiphyllum guatemalense ‘Monstrose’, often nicknamed the “Curly Locks Cactus” or simply “Curly Epiphyllum,” is a bizarre and beautiful cultivar of a jungle cactus native to the rainforests of Guatemala and parts of Central America. In the wild, the species (Epiphyllum guatemalense) grows as an epiphyte—anchoring itself to trees in humid, shaded environments where it absorbs moisture and nutrients from the air and rain.

Description

The ‘Monstrose’ variety is a cultivated mutation prized for its fantastically twisted and contorted stems. Instead of the flat, strap-like stems typical of most Epiphyllums, this form sports irregular, curled, ribbon-like growth that gives the plant a wild, untamed appearance. It’s a conversation piece in any collection, often grown in hanging baskets where its spiraled stems can cascade downward like abstract green ribbons. While its unique foliage is the star of the show, it may occasionally produce large, white, night-blooming flowers in the right conditions, though flowering is rare in this cultivar.

Care Tips

As a tropical epiphyte, Epiphyllum guatemalense ‘Monstrose’ prefers filtered light—bright but indirect. It will scorch in direct sun, especially during the hottest parts of the day, but too little light will slow growth. Morning sun or dappled shade is ideal.

Use a very well-draining potting mix—an orchid or cactus mix with added perlite or bark chips works well. Water thoroughly when the top few centimeters of soil feel dry, and reduce watering in winter. Avoid letting it sit in soggy soil, as this can cause root rot.

It thrives in warm, humid conditions but is surprisingly tolerant of indoor dryness if not overwatered. Fertilize lightly during spring and summer with a diluted balanced fertilizer. Prune unruly or overly long stems to maintain shape or encourage branching.

With the right care, Epiphyllum guatemalense ‘Monstrose’ is an easygoing, eye-catching plant perfect for tropical-style gardens, shaded patios, or as an indoor hanging feature. Its eccentric growth habit adds texture and a touch of whimsy wherever it grows.

CULTIVATION TIPS

We recommend purchasing 2 or 3 cuttings when planting up a pot as it will ensure the development of a robust and aesthetic plant.

Epiphyllum do best in partial shade in a fertile soil mix. Keep reasonable moist throughout the year, a little less so in winter. They enjoy humidity and so benefit from spraying.
