Blue Waterfall trailing bellflower

Notes

'Blue Waterfall' trailing bellflower (Campanula poscharskyana 'Blue Waterfall') is a perennial. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full or part sun. It grows quickly and blooms from spring to fall with starry blue to lavender blue flowers. It stays 4 to 8 inches tall and spreads 12 to 24 inches. If it looks tattered after heavy bloom, shear it down to a few inches to encourage fresh foliage and flowers.

Pairs well with Purrsian Blue nepeta, Carlton daffodil, and Angel Cheeks peony.
