Frost / dormancy
It was asked in another thread about which plants can handle a frost or two before coming inside, and which plants might even benefit from it, maybe be inspired to flower. I don't know if I have any plants that can be frosted without defoliating, which I think would be the deciding factor, so look forward to whatever experiences have been had.
About defoliation, it seems like the beginning of winter is a bad time to allow defoliation if one doesn't have a (cooler/darker?) place where dormancy could be maintained. Some people have greenhouses, so that's great, but if you don't... Won't they be confused trying to grow renewed "spring foliage" at the beginning of winter? It seems best not to induce dormancy in a plant if it's going to live in a fairly warm, sunny spot all winter, but that's just a hunch.
The only plant I have that seems to go dormant anyway is Persian shield. I've never brought one inside that didn't soon drop most of its' foliage.
I've decided to leave stuff like sweet potato vine, most of the T. zebrina, Tahitian bridal veil (Gibasis geniculata,) Datura outside where they won't be taking up space inside, but will have to grow back from the roots in the spring.
This also reminds me, my Mom has been saying for years that a lot of plants will be OK in frost if they thaw before the sun hits them. Like the rapid thaw is what actually does them in. It's not an easy thing to experiment with, but after watching things on those few special fall days for a few years, I think she's right. Plants on the west side of the house or in AM shade from a tree, in general, retain their foliage a bit longer.
I'm more confused than I was when I started writing this. oops!
