Outdoor Orchids

This list of orchids for growing outdoors is to give you some suggestions for the more hardy types.   However, they may need frost protection.   During the coldest parts of the year you may have to move them under a tree, a patio, or some shade cloth.   These orchids represent the easiest to grow, the hardiest, and easiest to obtain.   The links will take you to the culture sheet if there is one available.   Also see the expanded outdoor orchid list.
