Botanical name: Vanda spp
Vanda Orchids are popular due to their showy, fragrant, long-lasting and intensely colorful flowers where numerous flowers grow on a lateral flower spike arising from the central stem.
Most Vanda Orchids flowers show a yellow-brown color with brown markings but they also appear in green, white, red, orange, purple, pink and burgundy shades. The lip has a small spur. These orchids bloom every few months and the flowers last for 2-3 weeks.
The growth in Vanda Orchids occurs from a single stem and the leaves are highly variable and adapted to their habitat. The stems vary considerably in size with some growing up to 20 ft tall.
Vanda orchids are monopodial orchids which do not have pseudobulbs but they have leathery, drought-resistant leaves.
Vanda Orchids have very large root systems which may require that they be grown in hanging baskets inorder to suspend the roots for adequate room.
These Vanda Orchids do not tolerate disturbance or damage to roots and it can result in the orchids failing to flower and declining in growth for a season or more.
Vanda Orchids prefer very high light conditions, warmth, high soil moisture content and regular feeding. If a Vanda Orchid is provided with these conditions it will bloom at any time of the year.
Vanda is a genus that is widespread across East Asia, Southeast Asia and New Guinea. Most are epiphytes but some few are terrestrials. The genus name is abbreviated as V. in horticultural journals.

Pot the Vanda Orchid cutting in fresh orchid soil and place the set up in a warm shaded place.
Water thoroughly until water comes through the drainage holes and allow the soil to dry out between waterings.
Vanda Orchids naturally produce "baby" orchids called 'keiki' which normally appear on an old or new flower spike. Keikis are identical copies of the parent plant.
Keiki growth can be triggered by prolonged exposure to high temperature during the final phase of spike growth.
The keiki can be detached from the mother Vanda Orchid when about one year old when it has developed 2-3 leaves and 1-3 in. long roots.
Pot the Vanda Orchid keiki in fresh potting medium. Direct the roots of the Vanda Orchid keiki downwards and provide support for the keiki.
Place the set up in a well-lit, shaded place and mist the keiki regularly to maintain a humid enviroment.
Allow the new Vanda Orchid to be well established before transplanting it.
