Canterbury Bells is an old-fashioned biennial that blooms in early summer with large, showy flowers in shades of pink, purple and white. Great for cutting.
Campanula medium blooms the second year from seed. When it's done flowering, pull up the dying plants and shake the seeds over the area where you want them to grow next year.
This heirloom flower has been loved by many generations of gardeners. Deer resistant. Hardy in zones 5-8.

Campanula americana is a native wildflower with blue-green leaves and very tall stems of violet-blue flowers from July to October. The 1" wide flowers have five petals, and they are flat, rather than bell-shaped like most campanula species. They attract hummingbirds and butterflies.
Campanula americana is a biennial that self sows prolifically to replace itself. Plant it at the back of the border or wildflower garden with other tall perennials and shrubs that won't be overwhelmed by it. I enjoy it with Chinese trumpet lilies, which bloom around the same time.
Campanula americana prefers average to moist soil and part sun to full shade. Also known as Tall Bellflower and Campanula americanum.
Seeds require 4 weeks pre-chilling. Hardy in zones 3-8.
Campanula carpatica Blue
1200 seeds $2.25
Campanula carpatica is a gem for the partly-shaded rock garden or woodland garden. It blooms in mid summer with lavender-blue, cup-shaped flowers over low mounds of foliage.
I like this wild strain of Campanula carpatica better than the more compact "improved" varieties because the flowers look graceful on taller stems.
Also known as Blue Tussock Bellflower. Hardy in zones 3-8.
Campanula glomerata 'Superba'
100 seeds $2.75
Campanula glomerata 'Superba' is a reliable, spreading perennial that blooms in early summer. The stems are topped with dense clusters of rich violet-blue, bell-shaped flowers. It may repeat bloom if cut back after the first flush is over. Campanula glomerata 'Superba' makes an excellent, long-lasting cut flower. It goes well with many other flowers in the garden or the vase. It's a wonderful companion plant for roses. Shown here with California poppy 'Mission Bells'.
Also known as Clustered Bellflower and Campanula glomerata var. superba. Hardy in zones 3-8.

Campanula rotundifolia is a beautiful wildflower with violet-blue, bell-shaped flowers from June to September.

Campanula rotundifolia is drought tolerant, and it prefers well-drained soil. It self-sows in moderation.
