|Blooms early summer to late summer|
Campanulas provide long-lasting displays of showy, bell-shaped flowers in lovely shades of blue and occasionally white and pink. Each plant has two distinct leaf forms. Those at the base are rounded, while the leaves borne aloft stems are long and straight. There are low-growing species that provide summer color in the rock garden and taller varieties for the flower border.
Easily grown and much loved for their charming blossoms, garden Campanulas are often noted as prime fillers of the "June gap", the relatively flowerless two-week period between the end of the spring explosion of bloom and coming of the Roses and other perennials of high summer, such as Coreopsis, Monarda, and Salvia.
A large genus of plants with a wide range of growth habits, most Campanulas are very floriferous and have bell-shaped flowers, blooming late spring into summer. Plants prefer sunny locations with well-drained soils.
