Homestead is just south of Miami, on the way to the keys. There are about a dozen growers in Homestead. My favorite for cattleyas is Carib Plants. They're hard to find so take a GPS. B&G Orchids is a good vendor. Ruben in Orchids is more likely to have species rather than hybrids. The Redlands Orchid Festival is May 15th through the 17th. What dates will you be in Florida?
