June 13th General Meeting:

Bill Thoms on ‘Orchid Hunting in the Philippines’

Our June guest speaker is a man of action and adventure, who has risked life and limb to give us a rare and frequently humorous look into the ‘wilds’ of the Philippines. His six-week search for the elusive and rare Bulbophyllums in untouched forests of the Philippines will bring you face-to-face with parts of nature rarely seen by outsiders (don’t forget to wear your insect repellent)! Bill’s presentation will also include bulbophyllum growing tips and techniques gleamed from over 47 years of experience. No matter whether you have 1000s of orchids, just a few, or none at all, Bill will give you tips to make any plants grow and bloom better.

About Bill

It all started innocently enough around 1968 when Bill decided to rescue plants of Encyclia tampensis in Ft. Lauderdale,  Florida  (He actually just picked them off trees pushed over for a new condo, but it sounds better). He moved to the Tampa area in the early ‘70s and eventually meet his wife and life partner Doris Dukes, a highly accomplished grower in her own right. Together they ran a retail orchid nursery for 30 years called Hilltop House. They have since retired from the retail business but have continued on with their highly successful Bulbophyllum hybridizing program.

Bill has received more awards for Culture in just Bulbophyllums than anyone else in the world (47 so far) – and he and Doris together have 95 Cultural Awards in 30 different genera. Bill also received one of the most prestigious awards given to a hybridizer, an ‘Award of Distinction’ which is given for a worthy new avenue of breeding. The American Orchid Society has added a new Annual Award for the Bulbophyllums, the Bill Thoms Award.


Orders may be placed with Bill for plants, flasks, and his wonderful book, Bulbophyllums; the Incomplete Guide, From A to WHY? Just go to his site select your desired items and send him an email with your items and be sure to tell him that you are with the Sonoma County Orchid Society. He will bring your order to the June 13th meeting for you.
