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. It is our hope that our site, our meetings, and our members will spark your enthusiasm to give this most satisfying hobby a try!


Announcing the 1st Annual Pacific Orchid and Garden Exposition

Due to its success, the society’s number one fundraiser, the Pacific Orchid Exposition, is becoming the Pacific Orchid and Garden Exposition (POGE). Next year’s show will have thousands of orchids from around the world, but also specialty plants, gardening supplies, equipment and landscaping materials from only the best suppliers. As a result of this expansion, we are MOVING to the Cow Palace. (View more information).

July Speaker: Phyllis S. Prestia (Vice President of the Cymbidium Society of America) - OCA Tour of Madagascar

Phyllis S. Prestia is a retired educator and Middle School Principal. She received a Doctorate of Education at Rutgers University, where she also served as instructor in the graduate education program.
Originally from New Jersey, she moved to California with her husband to retire in the sunny, San Diego area and grow orchids. Her collection includes a variety of species and hybrids across several genera grown both in a small greenhouse and three outdoor growing areas under shade cloth.
In her orchid life she has been the President of the San Diego County Cymbidium Society and currently serves as the Vice President of the Cymbidium Society of America, as well as keeping active in several Southern California orchid societies. She is currently a probationary judge for the American Orchid Society.


Phyllis spent nine days trekking through the rainforests in Madagascar. She will highlight the species she saw and photographed with an emphasis on Angraecoids.

As she also grows many of these species, she will review the culture for these orchids, including tips from her own successful experience growing them. Together with knowledge about growing conditions in these rainforests, hobbyists will gain a greater understanding of how to adapt their growing environments for success.

July Skill Session: Debra Atwood of Napa Valley Orchids - She will also bring plants to sell.
