We promote the exchange of information and research regarding all aspects of orchid culture, not only for the education and benefit of the members of the corporation, but for all members of the public who are interested in orchids and their culture, hybridization, display, arrangement, and exhibition. We actively promote and support the conservation of various endangered orchid species and the preservation of orchid habitat, as well as our educational and research missions through annual grants to local, national and international applicants.
