June Speaker: Fred Clarke - Australian Dendrobiums and their culture

Join us for Fred Clarke’s presentation on Australian Dendrobiums and their cultivation. These orchids from down under flourish in the Bay Area and are not commonly found at your local box store. Aussie Dendrobiums are easy to grow, tolerant of heat and cold, have fragrant flowers, and re-bloom from the old bulbs!!! They grow well with Cattleyas and in frost free areas they are perfect plants for the shade house. Fred will also cover the best practices for growing these remarkable plants to help you achieve the very best results.

About Fred

Fred Clarke has been growing orchids for 40 years and has been hybridizing for 37 of those years. With over 35 years as a professional grower and manager in the horticultural industry, Fred applies these skills at his orchid nursery; Sunset Valley Orchids, located in Vista, California.

He is a passionate orchid grower whose curiosity in orchids is broad and varied. Although developing Cattleya hybrids has been his sustaining interest, he is also actively creating new Aussie Dendrobium and Paphiopedilum hybrids.

His pioneering work in Catasetum intergeneric hybrids led to the development of several notable hybrids, most recently the grex, Fredclarkeara After Dark, which produced one of the blackest flowers ever witnessed. This grex has received eight FCCs, eight AMs and the coveted AOS Award of Distinction on the first flowers shown for judging!

Fred is an Accredited Judge in the Pacific South Judging Region. His plants have received hundreds of quality awards from the American Orchid Society.

Skills Session at 7pm: Dean Hass of Botanico will lead a Q&A session on general repotting and deflasking.
