Historic Paphs: Passions and Paradigms of 150 Years
(May 23, 2022)

Tim is holding Paph. Yerba Buena 'White Caps' HCC/AOS, an exceptionally important cultivar in the development of modern green and white complex paphs. This cultivar was awarded in Oakland in 1967.

What makes a good program for an orchid society? Knowledge and enthusiasm, for starters! The speaker has to know the subject, of course, but it is also necessary to convey the excitement of these oddly enticing flowers, and to carry the audience along on a journey of discovery. Tim Culbertson definitely has the knack for teaching, whether for a big, formal lecture or for an impromptu conversation with a novice who wanders into our AOS judging center and is curious about some unusual plant. We always look forward to Tim's original and well-considered presentations. Here's what he has to say about himself and the program:

Paphiopedilum British Bulldog, a descendant of the famous Paph. Winston Churchill 'Indomitable' FCC/AOS, originally produced by Stuart Low Nursery in England in the mid 1940's, and exported from England as a seedling.

"Although I teach middle school kids for a living, one of my passions has always been plants. I began growing orchids as an offshoot from working at Longwood Gardens in Philadephia just after college. From the very beginning it was all about Paphs, particularly awarded and select clones of historic importance, of which my collection numbers nearly 3,000. While I love finding old, rare stepping stones in Paph breeding, I also do a little hybridizing of my own, and growing up my own babies is a blast. I am the youngest accredited judge with the American Orchid Society, and have served in various capacities with various orchid societies in California and on the East Coast. I love meeting other people who like orchids too, and doing so often finds me traveling to shows, vendors, and peoples’ greenhouses to see the latest and greatest in new hybrids and to get the best orchid gossip. I like to be involved in plants as much as possible: in addition to Longwood, I’ve worked at the Smithsonian Institution tending to their orchids, and for years for the United States National Arboretum, collecting rare plants and documenting cultivated species and hybrids for their herbarium. In short, I really like plants.

"For your meeting, I’ll be sharing a presentation entitled “Historic Paphs: Passions and Paradigms of 150 Years”. One of my absolute favorite parts about collecting orchids is thinking about their history, and Paphs have an especially rich history. I will share some of the important cultivars still in existence, and stories of their owners, breeders, and movements from one nursery to the next. These stories shed a new light on how we have gotten where we are; they provide a background for modern plants and why they are so important and so special. Southern California has an important role in these stories! By the end of this presentation, you will have a new appreciation of the history of important nurseries and collectors and collections, as well as breeding trends for these types of plants, and an appreciation of their beautiful flowers."


Encyclia ambigua
Encyclia adenocaula

For our May, 2019 meeting, Tim tackled the group of New World orchids known as Encyclia, from "Mexico and Beyond". These spectacular Cattleya relatives grow well outside in Southern California, and with their compact habit, great fragrance, and ease of growth, these are delightful plants for every collection. By extending the traditional definition of Encyclias to include recently-separated groups like Anacheilum, Panarica, Prosthechea, Euchile, and others that Tim says he and many others grew up calling Encyclia (maybe that's how Tim first knew them, but some of us at South Coast Orchid Society go back far enough that we still think of them as Epidendrum! — And now, a BIG THANK YOU to the taxonomists for giving us so many possible names, each more difficult to spell than the last ones they proposed, for these otherwise delightful plants), we end up with a diverse, beautiful, fragrant, exciting group of plants and flowers; if we add those to the wonderful flora of Mexico and Central America, we have a group that every collector should grow. What an enjoyable program!

Encyclia tampensis

Quite a few Encyclia and related species have been used in hybridization, but it seems to us that their potential is only beginning to be appreciated. Relatively few of the registered hybrids have found a wide following in the trade or on judging tables. One recent exception is the interesting hybrid Guaricyclia Kyoguchi (Guarianthe [=Cattleya] aurantiaca x Encyclia incumbens [=aromatica]), which produces clouds of bright yellow flowers with a pretty lip, and a few clones with semi-alba flowers. This hybrid is now turning up as seedlings (sibling crosses from selected cultivars) and also as a parent in new hybrids at Sunset Valley Orchids.

Another strategy is to cross interesting Encyclias with large or floriferous Cattleyas. Two impressive examples are shown here, Guaricyclia Voila (Guarianthe bowringiana x Encyclia cordigera) and Catyclia Florida (Cattleya dowiana x Encyclia cordigera).

There is a lot of natural variation in many of the Encyclia species: alba varieties, variations in the size and color of the lip, varieties with much darker petals, etc. There are also Encyclias (and varieties) with many different fragrances, such as raspberry or chocolate. Watch for new hybrids!
