Lepismium houlletianum (syn. Rhipsalis houlletiana) - Snowdrop Cactus

Lepismium houlletianum (syn. Rhipsalis houlletiana), commonly known as the Snowdrop Cactus, is a graceful epiphytic cactus native to the rainforests of Brazil. This easy-to-grow succulent is admired for its flattened, lanceolate stems and charming white flowers. With its unique appearance and adaptability, Lepismium houlletianum is a delightful addition to any plant collection.

Distinctive Features

• Flattened, Lanceolate Stems: The most distinctive feature of this cactus is its flattened, lanceolate stems, which can grow up to 60cm (24in) long. These stems are typically a vibrant green and have a smooth texture. The edges of the stems are often serrated or notched, adding to their visual interest.
• Charming White Flowers: In spring and summer, Lepismium houlletianum produces charming white flowers along the edges of its stems. These blooms, though not particularly large, add a touch of elegance to this unusual cactus.
• Epiphytic Growth Habit: As an epiphyte, Lepismium houlletianum naturally grows on trees in its native habitat. This means it prefers a well-draining potting mix and benefits from good air circulation around its roots.

Care Tips

• Light: Bright, indirect light is best for Lepismium houlletianum. While it can tolerate some shade, it will produce more flowers in brighter conditions. Avoid direct sunlight, which can scorch the stems.
• Water: Allow the potting mix to dry out slightly between waterings. During the growing season (spring and summer), water moderately, and reduce watering in autumn and winter when the plant is dormant.
• Humidity: This cactus prefers slightly higher humidity than desert cacti. Misting occasionally or placing the pot on a tray of pebbles and water can help create a more humid environment.
• Temperature: Lepismium houlletianum thrives in warm temperatures between 18-24°C (64-75°F) during the growing season. In winter, it can tolerate cooler temperatures down to 10°C (50°F).
• Fertiliser: Feed with a balanced liquid fertiliser diluted to half strength once a month during the growing season to support healthy growth and flowering.
• Potting: Use a well-draining epiphytic cactus potting mix. Repot every 2-3 years in spring to replenish nutrients and accommodate its growth.
• Propagation: This cactus can be easily propagated from stem cuttings. Take cuttings in spring or summer, allow them to callus over for a few days, and then plant them in a well-draining potting mix.

Additional Notes

• Lepismium houlletianum is a relatively fast-growing cactus and can quickly fill its container, making it a rewarding plant to watch develop.
• This cactus is not toxic to pets, but it's best to keep it out of reach of curious paws and mouths.
• With its unique appearance and easy care, Lepismium houlletianum is a delightful addition to any plant collection, bringing a touch of the rainforest to your home.
