With the publication of Genera Orchidacearum volume 6, the tribe Vandeae has been revised. Many familiar genera are now included in Vanda. Those genera still have listings in Orchids A to Z under their previous name with notation indicating their inclusion in Vanda. Among those now included in Vanda are Ascocentrum, Christensonia, Euanthe and Neofinetia.
The derivation of the name Vanda comes from the Sanskrit word referring to the plant we now know as V. tessellata. These popular plants are found in tropical areas, requiring lots of bright light, plenty of water, warm temperatures (an exception being V. coerulea which is native to higher elevations) and high humidity. The flowers are showy and colorful and when hybridized with Ascocentrum to produce Ascocenda, available in just about every color imaginable.
Taxonomically it is a genus rife with confusion and many species have been (are in some cases still are) treated as separate genera an example being V. sanderiana which is also known as Euanthe sanderiana (for specific information on this species see Euanthe) to the disagreement of some taxonomists. Although now known as Papilionanthe, the terete-leaved P. teres was not long ago known as Vanda teres.
Vanda species are generally tall monopodial plants that usually bloom but once a year. Combined with Ascocentrum, plants that bloom several times a year are produced. The leaves are strap-shaped as opposed to the pencil shape of Papilionanthe species. The leaves of Vanda usually have erose (uneven and irregular) cut tips. The flowers which range in size from 1 to about 4 inches are very popular. Many of the species are very fragrant and the flowers long lasting. Much hybridizing is being done with many of the species that were relatively unknown a short time ago. Thus in collections, it is easy to find commonly grown species such as V. coerulea and V. denisoniana growing beside some of the lesser known species such as V. dearei, V. lamellata or V. merrillii.
Widespread in tropical Asia from India, east to Southeast Asia, Indo-China, New Guinea, Australia and the Philippines to Taiwan and the adjacent islands.
Most are warm-growing; some species from moderate elevations (e.g. V. coerulea)are intermediate growers.
Usually in baskets with little or no medium. Pots are acceptable. Plants should be disturbed as infrequently as possible.
