- Description
-
Queen of the night is a tropical epiphyte to lithophyte and spineless cactus with aerial roots and large, fragrant flowers. It is native to Central America and thrives in tropical and subtropical climates rather than in dry, arid areas. In its native habitat, it is found growing on other plants or trees as well as rocks and may grow up to 10 feet tall. This member of the cactus family (Cactaceae) is the most cultivated species in the genus.
This plant requires bright, indirect light and protection from the harsh afternoon sun. Give this plant a well-drained average succulent or cactus potting mix with added sand or perlite. Soak the soil completely when watering, and water regularly during the spring and summer. Allow the top of the soil to dry out between watering. Reduce the water schedule during the fall and winter when growth is slowed. It is not frost tolerant and prefers temperatures between 50 to 80 degrees Fahrenheit. It thrives in high humidity, and a humidifier may be needed. Repotting may be required every 2 or 3 years. The queen of the night can be easily propagated by stem cuttings.
The plant is erect, sprawling, and spineless cactus. It is commonly grown as a smaller ornamental houseplant. It has long, flat, green segmented stems or leaf-like branches that may have wavy or lobed edges and measure up to 16 inches long. The flowers are white, fragrant, waterlily like and measure 12 inches long and 8 inches wide. They are night-blooming and wither by the next morning. They typically bloom in the late spring to early summer; however, houseplants tend to bloom sporadically. The flowers are pollinated by bats and moths. After flowering, purplish-red fruits are produced that are edible.
The queen of the night has slightly different growing needs than other cacti or succulents. If you are up for the challenge, you will be rewarded with a beautiful and unique houseplant.
Insects, Diseases, and Other Plant Problems: Common insects include mealybugs, spider mites, and scale. The plant is susceptible to root rot in the presence of overwatering or poorly drained soil. Powdery mildew can occur if the air circulation is poor. Exposure to direct sunlight can cause sunburn.
