The San Francisco Orchid Society (SFOS) is an Internal Revenue Service recognized Section 501 (c) (3) charitable corporation.
The SFOS is organized to promote and disseminate knowledge, information, and instruction concerning the culture of orchids, their hybridization, display, arrangement, and exhibition. Through this exchange of information, conservation of various endangered orchid species and the preservation of orchid habitat is promoted.
The SFOS schedules an annual exposition that serves as its major fundraiser and educational outreach program. In addition, smaller educational opportunities for the community, such as an orchid fair with educational talks and sales, are scheduled at various times during the year. Lectures and skill sessions on the species and their care and culture take place on a monthly basis at the regularly scheduled meeting of the Society.
Activities that the San Francisco Orchid Society schedules for its members only include excursions to orchid-related facilities, like commercial or private greenhouses.
