An unusual form of Jacob’s Ladder, this plant forms a lush mound of ferny foliage in a stunning black-purple shade, later becoming green. Upright stems of soft blue phlox-like flowers appear in late spring. An unusual plant for the woodland garden or edging in the border. Nice as a cut flower. Evergreen in mild winter areas. Easily divided in early spring or fall. Also tends to self seed and most seedlings should show the desirable dark foliage.
