Question
Looking for a grower / exporter of native Belize Orchids

Answer
I recommend that you contact any of a number of growers in the United States.  Oak Hill Gardens in West Dundee, Illinois artificially propogates species orchids from seed and Andy's orchids in California also specializes in growing species. You will need to know the specific species you want to grow.  Just google Belize orchids to find the species that grow there and then go to The Orchid Mall web site to the vendor section for growers or propogators of those species.
