Autumn Joy' refers to the beautiful masses of tiny, star-like pink flowers that emerge in September and gradually change to deep rose-red and then coppery-rust later in autumn. The flowers appear in large flattened heads, 3-6" in diameter, atop stems of soft grayish-green fleshy succulent-like leaves in upright to slightly spreading clumps. The name 'Stonecrop' refers to the frequent sighting of this genus in the wild, growing on rocks and stony ledges.
