If you visit just one botanical garden in Florida, choose Selby, which has the world's largest scientific collection of orchids and bromeliads – more than 20,000 species. Emblematic of Florida, these plants are the sideshow freaks of the plant kingdom, propagating in such bizarre fashion it boggles the mind. In addition, Selby's genteel outdoor gardens are exceptionally well landscaped and relaxing, with 80-year-old banyan trees, koi ponds and splendid bay views. Art exhibits, a cafe and an enticing plant shop complete the experience.
