Coral Cactus

Coral Cactus (Rhipsalis cereoides)

Other Known Names: Pencil Coral Cactus, Sea Coral Rhipsalis, Coral Mistletoe Cactus
Genus: Rhipsalis
Species: cereoides

Aesthetic Description

The Coral Cactus (Rhipsalis cereoides) is a graceful, coral-like epiphyte that captures the essence of the rainforest canopy in miniature. Its slender, cylindrical stems branch freely, forming soft, coral-inspired tangles that spill elegantly from hanging pots. The stems range in tone from fresh green to sun-kissed yellow-green, giving the plant a luminous, underwater quality that feels both organic and sculptural. When in bloom, delicate white flowers appear along the joints, creating a constellation of tiny stars across the branching stems. Effortless, airy, and texturally rich — this species brings a gentle, oceanic calm to any collection.

Colours

• Stems: Fresh green to yellow-green
• Flowers: Small, white to creamy blooms
• Fruits: Pale pink to translucent white berries

Scientific Description

Rhipsalis cereoides is an epiphytic cactus native to the tropical regions of Brazil. Belonging to the Cactaceae family, it grows naturally on tree branches, absorbing moisture and nutrients from the humid air and organic debris around it. Its thin, cylindrical cladodes resemble coral branches — hence the common name — and it is among the more delicately built members of the genus. Tiny, radial flowers bloom along the stem segments, producing smooth, berry-like fruits that serve as an important food source for forest pollinators. The plant’s slender architecture and fine branching give it a soft, pendulous habit ideal for hanging or elevated displays.

General Botanical Information

This species demonstrates the adaptive brilliance of rainforest cacti. Rhipsalis cereoides thrives in partial shade, where light filters gently through foliage, mimicking the dappled conditions of its native canopy. Its roots are shallow and adapted to epiphytic life, meaning it prefers loose, airy soil and high humidity. Easy to care for and visually distinctive, it’s a favourite among collectors looking to bring a more delicate and intricate texture into their plant spaces.

Growing Conditions

• Light: Bright, indirect light or light shade

• Watering: Keep soil evenly moist, allowing partial drying between watering

• Soil: Open, free-draining mix with bark and perlite

• Feeding: Apply diluted cactus or epiphyte fertiliser monthly in active growth seasons

• Humidity: Prefers moderate to high humidity levels

• Repotting: Every 2–3 years or when root-bound
