Birch Hybrid Campanula (Birch Hybrid Bellflower)
Shown here mingling with Mount Vernon Laurel, another excellent evergreen groundcover, this campanula stays low, blooms long into the summer, provides showstopping inch-and-a-half-ish stunning blue – purple flowers and behaves itself with almost no maintenance. Mostly sunny, dry, perched spots are a great place for them, but they’ll also work out with some irrigation or shade and a variety of other soils if they need to. They’re evergreen here in Seattle. Maybe a little deadheading after bloom if you’re a neatnik, but other than that…there isn’t anything that you have to do to this plant. The one shown here is above a rockery with sandy soil in morning shade and has not been watered in years. You can buy it just about anywhere in both 4″ and 1 gallon pots. Great in containers.
