There are many areas throughout the southern and central United States where temperatures for a good portion of the year are compatible with the needs of many orchids.
Some coastal areas are nearly frost-free year round.
In these areas, with some protection from excessive sun, wind and rain, lovely orchid plants can be successfully cultivated on the patio or as a part of the landscape. In frost-free areas, the plants can be left in place all year. The trick is in selecting plants that are already adapted to your particular area. First, though, consider some basic cultural needs of the plants. No flowering plant will do well in deepest shade, and orchids are no exception.
