Biennial, OP heirloom
If you like to grow cut flowers for bouquets, this one’s for you! Each plant provides masses of large, vivid purply-blue flowers on 18 to 36” tall scapes, from late spring through mid-summer. And Canterbury Bells are among the longest-lasting of cut-flowers. The only caveat is that you need to wait until their second year of growth to get flowers. First-year plants grow a low rosette of foliage. Definitely worth the wait! Grow in sun or part-shade in fertile, well-drained soil. Planting a group together helps plants support each other without staking, but in windy locations stakes may be needed. Plant 12-15” apart. Cold-hardy to Zone 5.
