Queen of the Night (Selenicereus grandiflorus) is a spectacular cactus known for its large, fragrant, night-blooming flowers. Native to tropical regions of Central and South America, this epiphytic cactus features long, trailing or climbing stems that are ribbed and often covered with small areoles bearing spines. Its real charm lies in its stunning white flowers, which open only once per night and typically bloom after dusk, exuding a sweet, captivating fragrance that attracts nighttime pollinators such as moths and bats.

The flowers are impressively large, often 6 to 12 inches in diameter, with multiple layers of delicate petals that create a dramatic, star-like shape. Because the bloom lasts for just one night, it has earned the poetic nickname 'Queen of the Night.' Blooming typically happens in summer, and the flowers close before dawn, making the flowering a fleeting but enchanting event.

Caring for Queen of the Night involves providing bright indirect light or partial shade, reflecting its natural habitat under forest canopies. It thrives in warm temperatures from 50 to 90°F (10 to 32°C) and prefers well-draining soil similar to other epiphytic cacti. Water moderately during the growing season, allowing the topsoil to dry out between waterings, and reduce watering in winter to prevent root rot.

This cactus appreciates high humidity but is adaptable to average indoor conditions. Due to its sprawling habit, it is ideal for hanging baskets or mounted displays where its long stems can be enjoyed. Fertilize monthly during the growing season with a balanced, diluted fertilizer to promote healthy growth and flowering.

The Queen of the Night cactus is prized not only for its remarkable nighttime blooms but also for its architectural elegance and relatively low-maintenance care. It is an excellent choice for collectors and anyone who appreciates dramatic, rare flowering cacti.
