Lately, my hanging baskets have been filling in very nicely. That purple and leaf plant has really taken off and it has been growing like crazy. I am have clipped off some starters and plan to grow it over the winter so that I can use it in baskets again next season.
The purple plant seems to look equally nice with both pink and red flowers and so I think it is worth trying to overwinter a few pieces of it. In addition, it seems to love the high humidity, because that's when it started growing like crazy!
