From Nan: Small warning on that violet. While it isn't on the California invasive list, it is really aggressive in southern California and I would expect it to be more so in Northern California. I was in a garden recently where it had overtaken the entire lawn and the owner was trying to figure out how to get rid of both the grass and the violets - and wasn't having much luck? I will double that warning. This gorgeous little violet got into my garden a few years ago. I was working too much at the time to weed carefully. It's now in the lawn and outgrowing everything, moss included, on the PNW coast. I'm considering a weeding torch to burn it out.
