Haha, I actually have that article already because I took my first classes in fruit tree care up at the CASFS farm. But luv ya anyway
Here's what Orin Martin (campus fruit guru) mentions about Tyson, in case others are reading: "Dawn and Tyson – I know nothing of these varieties’ source or origin but they are the ultimate summer sweet butter pear; a grafting project for the winter."
This is part of why I want to try Tyson--and even already have a healthy graft growing--and want to try Dawn but have never heard of anyone having a tree.* But they actually get a little more chill up there on the hill (campus is higher up, into the redwood and oak forests, I'm down near the water) so I just wondered if it would do as well down here. And our chill hours are so variable each year. I guess I can just cross my fingers! I haven't even looked up what we've totaled for chill yet this winter.
Hmm, now that I think of it, maybe I can get a scion from campus!
