Vanda Orchid

The Vanda orchids are known for their large, showy flowers. Like the distantly-related Phalaenopsis, they are monopodial orchids, but typically have many more leaves on the stem. They also like rather different growing conditions: in particular, Vanda light is guaranteed to cause sunburn in Phalaenopsis. These plants have very large, beautiful flowers in a wide range of colors; they have been widely hybridized to produce some very spectacular plants, and there are also many intergeneric hybrids with related orchid types.

(About orchid names)
Vanda coerulea supra, also known as Lord Rothschild's Variety, is the closest you'll find to a blue orchid. (There's no such thing as a truly blue orchid.)
The plants originate in parts of Asia, particularly Southeast Asia.

Vandas generally like warm daytime temperatures between 70°F (21C) and 95°F (35C), with a 10-15°F drop at night (6-8C). They also like high lighting, such as 3,000-5,000 footcandles, even more than Cattleyas. They can be gradually adapted to even higher lighting in many cases.

Try to provide humidity of about 70%. 50% is probably the least you can get away with.

They like a lot of air to the roots, so if you have enough humidity and can water at least daily, growing them barerooted in teak baskets works well. Otherwise, I suggest coarse orchid bark, charcoal, wine corks, or some other coarse potting mix, in a clay pot. Water as they approach dryness, as they don't have a way to store water.

Many Vandas can bloom 2-3 times a year.
