The yellow "Canna Cannova" (the tall Calla lily in the back) took off with a vengeance, as did the unidentified vine, to the detriment of some of geraniums and trailing purple flowers. I've even thinned out that vine a little!
Here's a photo of what it looked like when first planted, so you can compare the Now and the Then.
If the Canna Cannova doesn't survive the winter it will definitely be on the top of my list of favourites to buy again next year.
