Different types of orchids can be found growing everywhere from deep shade to full sun. The most commonly available orchids we grow at home need bright indirect light at a minimum, and in some case direct sunlight. We photographed this Brassvola orchid is growing in dappled sunlight along a riverbank in Belize.
Orchids are usually classified as warm growing, intermediate and cool growing, with regard to their temperature needs. Many tolerate exposure to warmer or cooler temperatures without suffering damage. The temperature groupings refer to the lowest temperature the orchid prefers during winter nights.
