Selenicereus grandiflorus is a cactus
Cactus
A cactus is a member of the plant family Cactaceae. Their distinctive appearance is a result of adaptations to conserve water in dry and/or hot environments. In most species, the stem has evolved to become photosynthetic and succulent, while the leaves have evolved into spines...

Etymology

Grandiflorus (Lat.) = large flowered. When Carl von Linné descripted this cacti in 1753 it was the largest flowered species of cacti

 known. Paradoxically, are moderate in size compared with several other Selenicereus species.

History

The first species to be brought into cultivation. Linné (Linnaeus) descripted it in 1753, but it was known long before. Records from Hortus Kewensis
Hortus Kewensis
Hortus Kewensis, or a Catalogue of the Plants Cultivated in the Royal Botanic Garden at Kew by William Aiton was a 1789 catalogue of all the plant species then in cultivation at the Royal Botanic Gardens, Kew, which constituted the vast majority of plant species in cultivation in all of England...

 gives that the species was grown at Royal Gardens at Hampton Court before 1700. There has been doubt about which plant was available to Linné when he drew up his description, but this is solved and both the plates on this side show the authentic species.

Origin and habitat

Greater Antilles (Cuba, Cayman Islands, Puerto Rico, Jamaica & Haiti), Mexico, Guatemala, Belize, Honduras, Nicaragua, and a few other locations in South and Central America. Climbing on trees and on rocks. 700m alt. Extremely variable, especially in Jamaica, stems with slightly wavy to strongly knobby margins occurs in the same plant. Much confused in cultivation. Many species of Selenicereus should be reduced to synonyms of subspecies

Cultivation

An easily cultivated, fast growing epiphyte

 or lithophytic plant. Needs a compost containing plenty of humus and sufficient moisture in summer. Should not be kept under 5°C (41°F) in winter. Perform best if grown in full sun. Extra light in the early spring will stimulate budding. Flowers in late spring or early summer, only blooms one night a year or several years and withers within hours.
