Our guest for the October meeting will be Ron Parsons. Ron has been growing orchids for more than 40 years and has been interested in and has grown species for most of that time. Ron loves to photograph orchids and other flowers whenever he can, whether it be in trips to see them in nature or in collections. Ron has nearly 60,000 digital images, most of which are orchids, and still retains a slide library that exceeds 100,000 botanical images. He has over 3000 published photos that have appeared in magazines, periodicals, journals and books. Ron has co-authored three botanical books, all with Mary Gerritsen. The first two, published by Timber Press, are Masdevallias, Gems of the Orchid WorldCalochortus, Mariposa Lilies and their Relatives. Most recently the third book, a large, luxurious 2-volume set A Compendium of Miniature Orchid Species was published by RedFern Natural History Productions.

Visitors are welcome to participate at regular meetings.

The Lowry Conference Center is located centrally in Denver at the corner of Yosemite Street and Akron Way. It has convenient free parking with direct access to the ground floor meeting room and free WiFi.

Picture of The American Orchid Society Guide to Orchids and their Culture

As a special offer to our members, DOS is obtaining copies of the new book “American Orchid Society Guide to Orchids and their Culture”.

From the AOS: “This book covers the basics of orchid culture including sections on light, water, temperature, humidity, fertilizer, and specific culture information on the popular groups of orchids. You will find information on when and how to repot, orchid mounting, and how to grow orchids semi-hydroponically. There is a section on common orchid pests and diseases, and the Orchid Doctor answers many frequently asked questions. Featuring more than 450 color photographs, The American Orchid Society Guide to Orchids and their Culture covers everything you need to know to grow orchids successfully.”

Offered by the AOS for $24.95, DOS plans to make a bulk purchase and offer the volume for $12.50 to our members and local enthusiasts. Arrangements will have to be made for picking up any copies you order, as we are unable to do any shipping.

If you have not already reserved a copy you may do so by emailing Lloyd Gelman at


The DOS Spring Show held at the Denver Botanic Gardens March 30-31 was a rousing success. We had good interest from the public and flowering orchids enough to please novices and experts alike. Thanks to our show chair Debbie Martin and the many volunteers that made it possible.
