I've got the Arrowhead Alpines milesii as well as 'Wildwood Willy'.
The
former is on its fifth winter in ground, even though I've got it
in such a
dry, shady location that it barely increases and has never
flowered. I'm
at a similar latitude as well (42.2°N). It's somewhat
protected by leaf
fall from a silver maple, but the ground around it
is defintely frozen
much of the winter, and it has taken at least
-10°F. I keep meaning to
move it, but like tectorum it looks so
pitiful by spring that I'm afraid
to touch it, even though they always
recover. Both species try to stay
evergreen, but the leaves are mush
by winter. I get the impression that
it's not really very damaging to
them.
I set rocks on bearded iris
that aren't well-rooted to help prevent
them from frost heaving in
winter.
