In every garden there are varying degrees of shade. There is the deep shade where serious woodland-type plants are the only thing that will grow. And then there is partial shade. Bliss: you can grow plants with flowers that will give colour and delight in those dark corners. Be careful: you do need a few hours of sunlight, but nothing like direct, full sun over the day.
Here are some of the nicest partial-shade perennials. They spread rapidly, so you may have to do some serious ripping out after a few years.
1. Bee Balm (Monarda didyma) — above
Bee balm, as the name hints, is heaven for the bees and hummingbirds. And the gardener: it comes in different shades of red and purple, it blooms in partial shade for weeks in July. If you cut it back, you may even get a second set of blooms in September. It spreads like crazy.
