Ron Parsons: The Genus Dendrobium

The Australasian genus Dendrobium is one of the largest genera in the most species-rich flowering plant family of the world. More than 1,800 species have been described (with likely many more to be discovered), and they are found anywhere from the lowland tropics to cool to cold high elevations. They occur from Japan and China to Australia in the south, and from India in the west to some of the islands of the south Pacific in the east. They occur in a vast variety of habitats too but they tend to generally grow as epiphytes and lithophytes with comparatively few growing terrestrially. Ron’s talk is a brief synopsis of this amazing genus that nearly every orchid enthusiast grows.

Ron Parsons has been growing orchids for more than 40 years, and has been interested in species orchids for most of that time. Ron loves to photograph orchids and most other flowers whenever he can, whether it be on trips to see them in nature or in collections. He loves to travel to see orchids in the wild, and does so a soften as possible. Ron has more than 80,000 digital images, most of which are of orchids, and still retains a slide library that exceeds 100,000 botanical images. He has 4,000 published photos that have appeared in magazines, periodicals, journals and books. Ron has co-authored four botanical books, all with Mary E. Gerritsen. The first two, published by Timber Press, are Masdevallias, Gems of the Orchid World and Calochortus, Mariposa Lilies and their Relatives. Our third book, a large, luxurious, 18.5 pound, two-volume set, A Compendium of Miniature Orchid Species was published by Redfern Natural History Productions in January of 2014, and has 1,200 pages, 1,800 photos (1,600 are his), and features 500+ species in detail with many others included for comparison. The most recent is The American Orchid Society Society Guide to Orchids and their Cultural which was released early in 2019.

Skill Session:
Chris Mende will give a basic intro on how to deal with seedlings and keikis. You will come away with more courage and ideas on how to grow these little babies into big plants.
