Helping You Become a More Successful Gardener

Towering skyward and the last of the bellflowers to bloom, chimney bellflower has heart-shaped leaves at the base of the summer-occurring flowerspike that bears white or light blue blossoms. A very short-lived perennial that is usually regarded as a biennial, this herbaceous plant is native to northern Italy and the Balkan States.
The medium to light green leaves are in a loose basal rosette, which each blade oval or lance-shaped with teethed edges. As early as early summer but often into mid- or late summer in the second year, a very tall flowerspike emerges from the rosette and displays fragrant, saucer-shaped, five-petaled flowers that are either light blue or white. Insect pollination leads to production of seeds; brown seeds will become blue-flowering plants while white seeds become white-blooming specimens.
Grow chimney bellflower in a rich, fertile soil that doesn't become soggy in full to partial sun. Seemingly slow growing in the first year, you are rewarded in either the second (sometimes third) growing season with the flowers. Stake the emerging flowerspike to prevent wind toppling and be aware of re-seeding of this short-lived perennial. Use it as a tall accent in the rear of a mixed border or among clumps of tall ornamental grasses for summertime splendor.
