Also known as "Clustered Bellflower". Easy to grow 4” violet blue clusters of upward facing flowers. Very cute filler in bouquets! Blooms late spring mid summer. Full sun, part shade.
 
Plant 1" deep.  Prefers well draining soil and fed a bit of compost at planting. Will tolerate clay and heavy soil as long as they do not get waterlogged especially during spring thaw.
Mulching around the base helps keep roots cool. This plant likes to be cool. Raised beds may get too warm for their preference.
