Be careful with indoor plants in drafts or where doors are propped open to frigid air.
(Read about it in Cold kills holiday plants.)
A reader alerted us that we missed addressing the following situation, in which tropicals can become pretty tough when it comes to handling drafts:
We keep a whole collection of plants in the lobby of the building where we have our office. They're just five or six feet from where a door opens to frigid air and people come and go all day. Sometimes people prop that door open while they move things in and out. - Eric Hofley, Publisher, Michigan Gardener magazine -

Good point, Eric. We've revised that article to put the emphasis on guarding new plants from drafts, along with those recently moved -- such as a begonia bumped from its usual place during holiday decorating.
Your note here says the rest, best: A plant that's been near a door throughout the fall has been gradually acclimating to increasing cold. It may well shrug off what would kill another of its kind that had no time to harden off.
