Climbing Cactus

Climbing Cactus is a common name applied to several species in the cactus family Cactaceae that have adopted a climbing or scrambling growth habit, clinging to trees, rock faces, and other supports using aerial roots or woody stems, rather than the upright or columnar forms typical of desert-dwelling cacti. Notable climbing cacti include species of Selenicereus, Hylocereus, and Epiphyllum, found in tropical and subtropical forests of Central and South America and the Caribbean. These species are often epiphytic or hemi-epiphytic, growing from forest floor to canopy by scrambling up tree trunks or clambering over rocks in humid forest environments. Many climbing cacti produce large, spectacular nocturnal flowers pollinated by bats and hawk moths, which are attracted to fragrant, white blooms opening for a single night. The dragon fruit (Hylocereus undatus) is the commercially most important climbing cactus, cultivated globally for its brightly colored, edible pitayas. Some climbing cactus species have very restricted natural ranges in tropical dry forests and coastal scrub and are threatened by habitat loss. Others have become invasive in parts of Africa, Asia, and the Pacific where they were introduced as ornamentals or for their fruit.
