White Doyenne is a common pear available, and Corvallis tends to only grow really rare hard to find types. They also may call it another name like Sementinum. It tastes wonderful. @marknmt originally told me about it, and @scottfsmith also grows it. You can read more on it here at the other link. A problem when growing it is what name do you find it under when buying it? Here are its names, among others. I would just ask for scions on the forum. Mine succumbed to fire blight.
