Selenicereus grandiflorus - Queen of the Night - Majestic Night-Blooming Cactus

Selenicereus grandiflorus - Queen of the Night

Selenicereus grandiflorus, commonly known as Queen of the Night, is a truly majestic cactus that deserves a place in any plant enthusiast's collection. This easy-to-grow epiphytic succulent is native to the Caribbean, Mexico, and Central America. It is admired for its large, fragrant, white flowers that bloom only at night, creating a breathtaking spectacle that is not easily forgotten.

Distinctive Features

• Spectacular Night-Blooming Flowers: The most captivating feature of this cactus is its large, fragrant flowers, which can reach up to 30cm (12in) in diameter. The petals are a pristine white, and the blooms release a heady fragrance that fills the air with a sweet, exotic scent. These stunning flowers typically appear in late spring or early summer and last for only a single night, making them a truly special event.
• Scandent Stems: The stems of Selenicereus grandiflorus are slender and scandent, meaning they climb or trail along surfaces using aerial roots. These stems can grow up to 10 meters (33 feet) long in their natural habitat, but they are typically much shorter in cultivation. They are typically green or bluish-green and have prominent ribs with small spines.
• Epiphytic Growth Habit: As an epiphyte, Selenicereus grandiflorus naturally grows on trees or rocks 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 Selenicereus grandiflorus. 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: Selenicereus grandiflorus thrives in warm temperatures between 18-24°C (64-75°F) during the growing season. In winter, it can tolerate cooler temperatures down to 5°C (41°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.

Additional Notes

• Selenicereus grandiflorus is a relatively fast-growing cactus and can quickly fill its container.
• This cactus is not toxic to pets, but it's best to keep it out of reach of curious paws and mouths.
• With its stunning, night-blooming flowers and easy care, Selenicereus grandiflorus is a rewarding plant for both novice and experienced plant enthusiasts.
