I've had this plant about a year and a half, and it has grown well in an indoor bay window. I get several blossoms during the warmer months. It has outgrown the bay window area and, as can be seen, it wants more space. I have no place to put it with southern exposure, particularly in the winter (I'm in the north). And it seems to need a trellis of some sort. I water it well, and spritz it frequently. I'm totally ignorant about growing these (or much of anything else for that matter). Does anyone have any suggestions for me? Thank you in advance.

Roger, to NGA.

You can keep large outdoor plants indoors IF you are willing to do a little pruning. Right now, decide on a shape and get out the pruning shears. Cut it back to just above leaf nodes - it will re-branch at those nodes. Try to encourage upward growth. I would cut all those branches going sideways back to just one or two nodes. The one's going straight up are good but you can encporage some bushiness by just taking off the top two leaves. Next winter, re-pot and do a little root pruning. You should be able (with top pruning and root pruning) to keep your plant healthy and contained.

Thank you very much for the advice. I will do as you have suggested.
