Blue mist shrub is aptly named as its gray-green foliage is shrouded in a cloud of blue from mid to late summer. It is a well-behaved garden plant that is very attractive to butterflies. 'Dark Knight' has deep purple blue flowers closely spaced on long stems.
This excellent variegated selection of P. reptans was selected by Bill Cullina of The New England Wild Flower Society. A good plant for shade or a sunny edge (with adequate moisture). Imagine, a variegated Polemonium that actually lives! This native groundcover is very popular, and its royalties benefit the Garden in the Woods and their plant and habitat conservation.
