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.
Where winters are cold, orchids can be grown on the patio or under trees in the warmer months when frost does not threaten. This is often a wonderful solution for orchid growers in colder climates, and enables the plants to grow so much better than they would if left indoors all year. Growers in frost-free areas with cooler summer nights (below 60 F in August and after) can grow cymbidiums, one of the finest of all garden orchids. Where summer nights are warmer, many varieties of vandas and cattleya types are appropriate.
