Your instincts are pretty good. I'm not sure you should be believing everything I say. For instance, two blocks from your tree is another tree that is thinner and paler than the 'Kanzan' nearby, but the flowers look like 'Kanzan' to me, and I figured it was just a sick tree. This tree is between 6th and 7th, east side, just north of the lane. But on the ground was a sprig that looks just like 'Pink Perfection' (4th photo), except for the bronze leaves. Did you pull that off your tree and carry it for two blocks?? If I had known you were going to be right there, I'd have asked you to look at the 'Kanzan' trees right there! Slocan, between 6th and 7th (location in photo name is wrong). I put them on the map last August pending checking that they really were 'Kanzan' and getting a posting. I'm just as glad I went out there myself. See next posting.
