Epiphyllum pumilum, a charming Orchid Cactus, is a delightful epiphytic cactus native to Mexico and Central America. This compact and easy-to-grow succulent is prized for its slender, arching stems and delicate, fragrant, white flowers. With its graceful appearance and manageable size, Epiphyllum pumilum is a fantastic addition to any plant collection, especially for those with limited space.

Distinctive Features

• Delicate, Fragrant Flowers: The most captivating feature of this cactus is its delicate, fragrant flowers, which can reach up to 10cm (4in) in diameter. The petals are a pristine white, and the blooms release a sweet, delicate fragrance that fills the air, especially in the evenings. These charming flowers typically appear in late spring or early summer.
• Arching Stems: The flattened, leaf-like stems of Epiphyllum pumilum are a vibrant green and can grow up to 30cm (12in) long. They have a graceful, arching habit, making this cactus ideal for hanging baskets or displaying on shelves.
• Compact Growth Habit: Compared to other Epiphyllum species, Epiphyllum pumilum has a more compact growth habit, making it well-suited for smaller spaces or growing in pots.
• Epiphytic Nature: Like many orchid cacti, Epiphyllum pumilum is an epiphyte, meaning it naturally grows on trees in its native habitat. This means it prefers a well-draining potting mix and benefits from good air circulation.

Care Tips

• Light: Bright, indirect light is best for Epiphyllum pumilum. While it can tolerate some direct sunlight, it's best to avoid intense afternoon sun, 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 appreciates slightly higher humidity than desert cacti. Misting occasionally or placing the pot on a tray of pebbles and water can help increase humidity.
• Temperature: Epiphyllum pumilum 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 encourage healthy growth and flowering.
• Potting: Use a well-draining epiphytic cactus potting mix. Repot every 2-3 years in spring to provide fresh nutrients and accommodate its growth.
• Propagation: This cactus can be 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.
