I suspect that Claude is right. I never tried a Stanley here because I
had no reason to believe they were hardy enough.
I did try Mount Royal and it was a wonderful tree for about 15 years.
Doug, I think you are underestimating just how hardy Mount Royal really
is. I have a min-max thermometer that, back then, was wired right on the
Mount Royal tree. In its first 5 or 6 years that thermometer recorded 40
below zero two different years. Also it was in an exposed location with
nothing to block the west or north wind that blows across a frozen lake.
That tree produced a good crop almost every year. I seem to recall it
had a sparse crop after those 2 coldest winters. Finally,the tree
started getting cracked, then dead, bark on the upward facing surfaces
of the main scaffold limbs. This did not start after a very cold winter.
I always wondered what caused that. It's been dead for about 5 years now.
