Prostrate Rosemary, snapdragon, pansies, Swiss chard.
In my zone in sheltered area these four will live all winter. If we get temps below 20 it is brief and I can bring them in garage or cover if it's only for a few hours. Plus we can eat the chard. I'm putting more chard in deck containers. Just planted it with seedlings Labor Day weekend do it will fill in and look like something in a couple weeks.
