Selenicereus triangularis, commonly known as Nightblooming Cactus, is an evergreen perennial vine native to tropical rainforests, dry forests, and rocky areas in the Caribbean. It can grow to a height and width of 15-25 feet (5-8 meters), often climbing over other vegetation or structures with the aid of aerial roots. The plant is characterized by its triangular stems and large, showy, white flowers that bloom nocturnally, typically during the summer months. These flowers are highly fragrant and can reach up to 12 inches (30 cm) in diameter, opening at night and closing by morning.

Nightblooming Cactus is valued for its dramatic floral display and is often used in tropical and subtropical gardens as an ornamental climber on trellises, walls, or trees. It is relatively easy to maintain, requiring minimal water once established and thriving in well-draining soil. While it prefers full sun or part shade, it can tolerate a range of light conditions. This cactus is not typically prone to diseases but can be affected by pests such as scale insects and mealybugs. It is also important to note that while it is not considered invasive, its vigorous growth habit requires regular pruning to keep it under control.CC BY-SA 4.0
