Cantebury Bells medium Double Mix - Campanula mix. This popular cottage garden plant has graced our gardens since 1596 and is imported from Spain. An excellent long-lasting cut flower. Try a few plants in a pot, for the conservatory or orangery, where they can grow protected. Beautiful! Sow this biennial directly in the ground and thin out or transplant. It is possible to pre-sow in a greenhouse and transplant later.
