Campanula spp There are many species in this perennial European genus, a few of which make excellent long-lived cut flowers. Most varieties flower in the second year, coming in shades of blue, purple, lavender, or white. Armitage suggests these be grown "north of zone 7," as they require ample vernalization and do best with cool summer nights. That said, ours did beautifully in Zone 7b. Crowns may be divided every year, or at least every 3 years. Seed may be started in late summer, overwintered in 3-4" pots, and transplanted in spring for flowering that summer. Space at 12 x 12 or closer for greatest yield. Netting is required for straightest stems in Canterbury Bells (C. medium), but C. persicafolia may do well without support. Prefers full sun to partial shade. Seeds Per Gram: 15,000

'Cup and Saucer' refers to the variety's combination of a large bell-like "cup" subtended by a whorl of petals that form a "saucer."This is a color mix that includes purple, blue, pink, and white. Very attractive for bumble bees that favor the bells as overnight sleeping quarters. Grows to 3' with... pricing and more
