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!

Next Meeting: Tuesday, June 4, 2019 – 7:00 p.m.

June Meeting: Carol Klonowski

Topic: Latest Vandaceous Intergenerics

Join us for the June general meeting when our speaker will be Carol Klonowski. Carol will explore the history of the Vanda genus and its primary hybrids, botanical arguments for and against recent taxonomic changes, and how those changes effect both familiar species and the recent explosion of intergeneric hybrids in this important orchid alliance. She will also share with us the tips and techniques on how many local growers successfully cultivate these tropical beauties in their Bay Area greenhouses.

About Carol

Carol Klonowski has been growing orchids since the 1980’s when a friend in Berkeley, California, gave her a Cattleya and it bloomed out with three big, dark lavender flowers and an intoxicating fragrance.  She built an entire greenhouse in her backyard to accommodate the precious plant, which only led her to buy more orchids.  Then another friend gave her a gift membership to the Orchid Society of California and it’s been a serious hobby and passion ever since.

Carol has served as Director, Vice President, and President of the Orchid Society of California for most of the past two decades and is currently an Accredited Judge with the American Orchid Society, California Sierra Nevada Judging Center.
