Campanula is a native perennial flower that many gardeners know as bellflower. While there are many varieties of campanula, most of these varieties range in color from blues to purples (with some white blossoms as well). Because campanula thrives in both sunny and partially shady locations and it will grow readily without extensive care, many gardeners enjoy growing it. Identify purple campanula in landscapes to determine if it will fit into your gardening space.
Recognize campanula as it grows in a landscape with its characteristic blossoms. While the blossom colors and sizes vary, most campanula varieties have a distinctive bell-shaped blossom. Some blossoms are large, some are small, some are wider and some are narrower. Some campanula varieties put forth clusters of bell-shaped blooms and other varieties produce single blossoms.
Check the foliage on a campanula to help identify it. The leaves of a campanula plant are a medium shade of green, slender and they usually alternate on the flower stems (growing alternately up the stem and not directly across from each other). Often the flower stalks will extend up high from the centers of the plants with the leaves growing abundantly around the base of the plant.
Look for campanula flowers that grow to average heights of between 1 and 3 feet (some as tall as 4 to 6 feet) with spreads of up to 4 feet for some varieties. Campanula typically blossoms in mid- to late summer and is hardy between USDA zones 3 and 8.
