I'm pretty sure the whole plant would survive indoors. Most people spray plants they bring in from outdoors to get rid of bugs. I just do cuttings of impatiens. I snip off a piece a few inches long and stick it in water. They get all wilty at first, but after a week or so they begin growing roots and you can plant them in dirt after that. I often don't get around to planting them for quite awhile, but they just coast along in the water and begin to bloom again.

The big problem for me is aphids. They always suddenly appear after i plant the cuttings. One solution is to swish the plant around in warm soapy water, and insecticidal soap is another way to get rid of the aphids. Don't forget to take cuttings of the cuttings, and so on!

See this posting. There is a lot of good stuff there.
