If you garden in Philadelphia, you’re probably a connoisseur of shade plants. We have big old trees hanging over narrow streets. We have tall row houses and looming apartment buildings that block sunlight. And many of us have small, dark backyards. It’s easy to get a hundred gorgeous shades of green packed into one garden, but the options are more limited for flowering shade plants.
You can’t go wrong with bleeding hearts and hellebores, but I have a special weakness for columbines. There are dozens of varieties, and in many cases the colors are exquisite–deep purples, pale yellows, dark reds and pearly blues. The flowers look like something from an alien landscape, and the buds look like tentacled sea creatures.
