I left my aloe (about 2' in diameter) outside during a brief, snuck-up-on-me
light freeze and the outside leaves died right off. The inside is still fine
and growing great, though. But mine also won't tolerate very much direct
sun - the 'leaves' shrivel up and turn red. So, I keep it in the shade and
bring it indoors for freezes (and I mean freezes only -- a week of 35 lo and
50 hi didn't hurt it a bit that I can see).
