I usually cut my plants way back and treat them as houseplants over the winter. They struggle along but bounce back when they go outside in the spring. This year I didn't cut them back and have them under HID lights. They are doing great. They did drop some leaves while adjusting to the new enviroment but are still blooming and putting out new growth.

butterfly, I grow mine inside year 'round in pots. They seem quite happy; they bloom :)

They are on a wide windowsill with southern exposure. How the following came to be was an accident :0

They grew onto the windowscreen, and I just left them that way. It's like a trellis, I guess. We live in the woods, so have no need for drapes; we prefer our living 'drapes'...

Just an idea you might try if it would work for you--
