Helene at Briggs Hill is one of my favorite vendors!
I bought all of my slippers from her as well as a bunch of other stuff. She has some unusual Bulbos. and her selection of Phrags is superb! Have you been to her greenhouse? It's worth a trip.
I've never been to the Roseburg show before. It's the Willamette, Umpqua & Pacific Orchid Societies Show & Sale. I don't know who the venders will be but I do know Briggs Hill will be there for sure, and I assume JC Tropicals, Babydragon Orchids, and the other usual suspects will be there as well. This years theme is "Jewels of Nature". The date is 10/11 & 12. I'm pretty sure it is judged as some of the folks from the Rogue Valley Orchid Society are taking plants up. I'm not sure if I'll be able to make it or not. The other half has made some other committments.
