This mound of lavender-blue flowers and aromatic, grayish green leaves up to 2 feet tall and 3 feet wide is great as edging or in a border, herb, or rock garden. It is an easy to grow, prolific bloomer that seems to be deer resistant. It blooms the whole summer and tolerates some shade. It also looks great with roses or on walls.
