NO, it will NOT survive a winter outdoors in anything but the mildest zone
9
and up climate. The graft is very vulnerable and even a hardy variety can
have the graft burst. YOu need to have it in a LARGE pot and bring it
into
the garage to overwinter.

Interesting. Guess Seattle, the Portland area and Victoria BC have moved up
a zone or two - tree roses are quite common and add an appealing formal
feature in all three cities public rose gardens. I also have a client that
has a number of well established tree roses that have wintered over quite a
number of years. Will it overwinter without protection in Ontario? Probably
not.
