Vanda orchids originate in Thailand, India, Vietnam, Laos, Sumatra and the Philippines. Vanda flowers are showy and can range in diameter from 1 to 6 inches. They come in a kaleidoscope of colors, ranging from Lavender-blue red. The flower spike, or inflorescence, emerges from the leaf axils. Leaves come forth alternately from the main stem. These orchids grow well in warmer climates and in higher light situations than most orchids. In climates where the winter is cold, the plants must be overwintered indoors.
