The tightly clustered bells of Campanula glomerata ‘Joan Elliott’ put on a rich show of purple starting in June in Maine. Hardy to Zone 3, this bellflower can reach up to 2 feet in height and doesn’t mind a bit of shade. The name Campanula glomerata translates from the Latin into small bell for campanula and tight grouping for glomerata. It is a Eurasian native, although it has naturalized here in the United States. In its native lands, it can be found anywhere from forests to scrub to grasslands and won’t tolerate wet feet.
