Welcome to the San Francisco Orchid Society

Welcome to the San Francisco Orchid Society web site. We are lucky to reside in one of the best parts of the country for the cultivation of orchids in the home, greenhouse, and garden.

May Speaker: Mary Gerritsen - Slippery Tales - Misadventures in Hunting Slipper Orchids

Mary Gerritsen has been interested in orchids for over 30 years since her
post-doctoral days in the late 70’s in San Diego. She has worked in the biotechology industry for many years, developing drugs for autoimmune disease, cardiovascular disease and cancer. Now semi-retired, she works as an independent biotechnology consultant and in her spare time, travels as much as she can to see orchids in habitat.

In the past ten years she has gone on orchid trips/treks to various parts of the US and Canada, as well as Mexico, Costa Rica, Panama, Colombia, Ecuador, Peru, Venezuela, Brazil, Borneo, Western Australia, Thailand and southern and western China. She has also traveled to various parts of Europe/Mediterranean to photograph the terrestrial orchids there.

Mary enjoys writing about orchids, and is a co-author (with Ron Parsons) of two books (Masdevallias, Gems of the Orchid World, and A Compendium of Miniature Orchid Species). She has also written articles for orchid magazines including Orchids and Orchid Digest. She has a collection of mostly miniature, cool growing species. Mary is currently the vice president of the San Francisco Orchid Society and serves on the board of directors of the Orchid Conservation Alliance.
