A widely adaptable and tough native that is a deer-resistant food for larval butterflies. The fine-textured foliage provides a dark green backdrop for the clusters of white flowers that appear in June and July.
Brilliant blue flowers with striking red calyces cover bright green foliage from mid-summer to fall, when the leaves turn deep red. A wonderful groundcover, it is a great choice for beds of spring bulbs because it emerges late, as the bulb foliage declines.
