I think so to Scalar, but with protection i would give it a good chance there, I think the sun shines more back there and shines brighter/warmer then it does here. so at sunny days, in winter, he will get his vitamins and will be able to recover better.
Good luck, greets.
p.s in summer you got much higher temp so he might pull out a new set of leafes every year. Over here he also put out new leafes (except for one summer) but most in late summer, the leafes are then not totaly developed so much more sensitive in winter. I think you wont have that problem.
