Mary GerritsenFebruary 13,2020: Mary Gerritsen; Growing Orchids Outdoors (with your bromeliads) in the Bay Area

Mary Gerritsen is an independent biotechnology consultant who has been growing orchids (mostly species) on and off for more than 30 years. Since relocating to the San Francisco Bay area in 1997, she started a collection of small cool growing miniature species such as Masdevallias, Porroglossums, Lepanthes, and other assorted tiny gems. She also has a second intermediate greenhouse, filled with larger species such as Angraecoids, Dendrobiums, Oncidiums, Laelias, Phalaenopsis and Bulbophyllums. She loves to see orchids growing in situ, and has made it her mission over the last few years to see as many as possible, with trips to see and photograph orchids (and other flora as well) in Canada, many parts of the USA and Mexico, and countries in Central America, South America, South East Asia, western Australia, and Europe, as well as South Africa and Madagascar.
She is the co-author of several botanical books: Masdevallias, Gems of the Orchid World; Calochortus, Mariposa Lilies and their Relatives; A Compendium of Miniature Orchid Species; A Bay Area Guide to Orchids and their Culture; and The American Orchid Society Guide to Orchids and their Culture, with fellow San Francisco Orchid Society member and well known photographer Ron Parsons.
Mary frequently lectures to orchid societies in the San Francisco Bay area and on occasion other societies throughout the US and Canada. She is on the board of directors of the Orchid Digest, the Chief Operating Officer and Treasurer of the Orchid Conservation Alliance, and is also a member.

Mary will have copies of her ‘Bay Area Culture’ book for sale.

The BSSF will be providing the plant table.
