In the spring, very small, sharply serrated leaves emerge a cool shade of blue green, a color reminiscent of the lovely Sedum sieboldii. They form a perfectly rounded, low mound that is perfect for edging the front of the border. As the plant ages through the season, the leaves expand and turn lighter green, forming a short, semi-upright clump. When late summer and early fall arrive, a massive dome of bubblegum pink, star-shaped flowers completely cover the foliage followed by deeper pink seed heads later in fall. This plant pairs perfectly with other fall bloomers like hardy garden mums, asters, and Black-Eyed Susans. Try a few in containers and at the front of the border.
