Virtual Meeting – Tuesday, January 11

We are pleased to have Tom Etheridge as our speaker, and his talk is titled: “Odontoglossums Then and Now: Has Anything Changed?”

Odontoglossums are among the most varied and colorful of the orchid family. Their intricate veining and spotting of the flowers has led to their being called “Butterfly Orchids”. Tom’s talk will be fun, inspirational and entertaining!

Tom Etheridge has been growing orchids for about 45 years, having first started out with vandas and cattleyas while growing up in Florida. Since the mid-1990s he has lived in Oregon where he now specializes in orchids that thrive in the cool Pacific Northwest – odontoglossums, masdevallias, and draculas. He is an Accredited Judge in, and chair of, the Pacific Northwest Judging Center, and he is a past Vice-President and Board Member of the AOS. Professionally, he holds a PhD in chemistry and retired in 2020 from a 25+ year career at HP where he was the company’s Carbon Footprint Program Manager.
