Good luck with the Torenia Hybrid, they can be picky types.. *if they dry out, they only give you one chance to rewater.. if you let them dry out again, they pout and die... at least my experience with them...* and over wintering, not sure.. LOT's of light...
Coleus does pretty good, you can even take and pinch some of the longer stems off and put in water, they'll root.. any time they keep gettting lanky on you, pinch again, and put that stem
into some water too..
Never tried the Sutera *Bacopa*, but try it, bring it in, keep it watered, well lit area...
The Purple Queen Setcreasea *Wandering Jew
Tradescantia pallida 'Purple Heart'* will do wonderfullllllllllll.. it's a great house plant
and also can be snipped off, the stem, and roots great in water....
*has little purple/pinkish flowers
by a window.. semi light/indirect light/full light, they're a good plant
And we lovvvvvvvvve rescue plants
good for you, for doing such a great job on them..
(I go to the local cemetary, and they throw out alot of geraniums there, and spike plants
and such.. so, rescues are a good thing!)
