Campanula carpatica 'Kathy' Campanula carpatica 'Kathy' Campanula carpatica 'Kathy' Huge, pale blue discs in summer. £2.60 Out of stock. Shoots emerge in spring and by mid-summer will carry a succession of these huge, open flowers of pale blue, often lasting until late summer or beyond. 'Kathy' is strong enough to grow with other (non alpine) plants along border edges etc. but will also remain as a neat mound on the rock garden. About 15cm (6") high. Not often seen, but this is an easy, likeable garden plant, not fussy as to soil or position and well even tolerate a bit of light shade. Very hardy and fully perennial.
