Selenicereus is a genus of the Cactaceae family, known for its strikingly beautiful, nocturnal flowers. This genus is native to the tropical regions of the Americas, ranging from Mexico through Central America to northern South America, with some species found in the Caribbean. Selenicereus species are commonly referred to as moonlight cacti, highlighting their night-blooming nature. These plants are epiphytic or lithophytic in nature, meaning they often grow on other plants or rocks, deriving moisture and nutrients from the air and rain.

Description

Selenicereus species are characterized by their long, slender, vine-like stems, which can either climb or trail over the surfaces they inhabit. The stems are typically ribbed, with areoles that produce spines. The flowers of Selenicereus are its most notable feature, being large, often fragrant, and predominantly white, opening at night and closing by morning. These nocturnal flowers are adapted to pollination by nocturnal creatures such as bats and moths.

Taxonomy

The taxonomy of Selenicereus has undergone several revisions since its establishment. It was first described as a genus in 1845. Over the years, molecular phylogenetic studies have helped clarify the relationships within the Cactaceae, leading to the reclassification of some species and the consolidation of the genus.

Ecology

Selenicereus species play a role in their ecosystems as sources of nectar for their nocturnal pollinators. They are found in a variety of habitats, from dry forests to rainforests, where they can be seen growing on trees or rocks. The adaptability of these plants to different substrates and their epiphytic nature contribute to their ecological niche.

Cultivation

Selenicereus is popular in cultivation due to its spectacular flowers and ease of care. These plants prefer a well-draining soil mix, bright indirect light, and high humidity, mimicking their natural tropical habitat. They are often grown in hanging baskets to accommodate their trailing growth habit. While they can tolerate periods of drought, they benefit from regular watering during the growing season.

Species

There are several species within the Selenicereus genus, including:

• Selenicereus grandiflorus – Known as the Queen of the Night, this species is famed for its large, fragrant flowers that bloom for a single night.
• Selenicereus undatus – Also known as the Dragon Fruit or Pitahaya, this species is cultivated for its edible fruit as well as its ornamental value.

Conservation

Some species of Selenicereus are considered at risk due to habitat destruction and overcollection. Conservation efforts are necessary to ensure the survival of these unique plants in their natural habitats.
