Vanda is a genus in the orchid family, Orchidaceae. There are about 80 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids.
Vandas are in the Vandae tribe and Sarcanthinae subtribe of orchids. They are native to the East Asian tropics, ranging from Sri Lanka to China to the Philippines to Australia. Vandas are monopodial orchids, meaning they grow from a single stem with roots emerging from the bottom of the stem. Vandas' leaves are alternating, climbing the stem in a ladder-like progression. Older Vandas frequently branch and, if left undivided, the plants can grow into very large specimens. Vandas flower from spikes that emerge from the central stem and poke out between the leaves, and they are known for very large, robust roots that are difficult to contain in any sort of pot or container. Vandas are not beginner's orchids as they require certain elements that can be hard to deliver at home.
