DVOS Monthly Meeting
Thursday, Jul 10, 2025, 07:00 PM
Contra Costa Water District, 1331 Concord Avenue, Concord, CA, USA
Our Speaker in June will be Carol Klonowski
Carol 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. She can recall going to monthly meetings where orchid legends such as the late Frank Fordyce would be available to answer the many questions an eager hobbyist could ask.
Carol is currently the President of the Orchid Society of California and an Accredited Judge with the American Orchid Society, California Sierra Nevada Judging Center. She is a Trustee for the American Orchid Society and writes for Orchids Magazine.

President's Letter
Dear Orchid Society Members,
Summer is officially here—a season full of growth, blooms, and the perfect time for dividing your orchids! As you tend to your collection, please consider setting aside divisions for our Fall Auction this September. Contributions from generous members and volunteers like you are vital in keeping our society thriving.
For those of you venturing into orchid hybridizing, I’d like to share a bit from my own experience. Hybridizing takes a great deal of patience—something I’ve come to appreciate over more than 30 years in the hobby. While it can be challenging (especially with unreliable flasking services), the results can be incredibly rewarding. It’s a slow process, often taking 5–7 years to see blooms, but well worth it for the dedicated grower.
I’ve included photos (above) of one such success: six seedlings grown by Fred Clarke of Sunset Valley Orchids from one of my crosses—Catyclia Anjanine Kvale (Cattleya Behrensiana × Encyclia randii f. alba). This hybrid is named after a former colleague from my time at the National Park Service, while working at Fort Point National Historic Site.
As you’ll notice, while the blooms share a similar color palette, the flower forms vary, which is part of what makes hybridizing so fascinating. My current breeding focus is on increasing flower count per inflorescence and introducing the coerulea gene into future generations. I may even have a flask from one of my recent crosses available at the auction—stay tuned!
Wishing you a summer full of growth, discovery, and beautiful blooms.
Warm regards,
George Su
President
