About Queen of the night
Selenicereus grandiflorus, commonly known as 'Queen of the Night', is an epiphytic night-blooming cactus renowned for its spectacular and fragrant white flowers that open only once a year, at dusk, and close at dawn. Its long, segmented stems trail gracefully, making it ideal for hanging baskets or climbing structures in warm climates, creating a dramatic focal point in any garden or greenhouse.
Native range
Mexico, the Caribbean, and Central America
Care tips
This plant requires bright, indirect light; intense direct sunlight can scorch its stems. Water moderately in summer, allowing the substrate to dry completely between waterings, and drastically reduce watering in winter. Use a well-draining substrate, specifically for cacti or an orchid mix with perlite. A common mistake is overwatering, which can lead to root rot.
