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.
Oncidiums (can be grown outdoors in summer, indoors in winter). Paphiopedilums (prefer low light). Phalaenopsis (prefer low light and rebloom). A little more difficult to grow, but extraordinarily beautiful, are the showy and fragrant Cattleya orchids, which can feature flowers of spectacular size.
