Thank you both.
I am reminded of the statement by my silviculturist friend: "Sure, sub-alpine firs grow in the most inhospitable of places - heavy snow bearing down, extreme cold, short seasons - but that doesn't mean they won't thrive at lower (more benign) elevations."
As a container gardener interested in the aesthetics (and not so much in the comfort of the plant) it's useful knowing which kinds can best tolerate my abuse!
