Also known as Blue Globeflower, this plant has showy, tight round clusters of blue, bell shaped flowers. The plants are 18 to 24 inches tall and flower in midsummer. Cut flowers can be used in bouquets. Removing faded blooms will prolong the flowering period and will prevent an over abundance of self sown seedlings. Clustered Bell Flower is very attractive planted in masses.
Like most Campanulas, it is fairly easy to grow and will tolerate most soil types except those that are very droughty. It does not, however, do well during prolonged heat and drought so should be watered under these conditions. Plants should be divided every 3 to 4 years when they begin to lose vigor. This is best done in the spring and is an excellent means of increase. Space plants 12 to 16 inches apart.
