'Autumn Joy' Sedum (Sedum 'Autumn Joy' or Hylotelephium 'Autumn Joy') is wildly attractive to butterflies, bees, pollinating wasps, and birds. A superb perennial for borders or rock gardens, it grows to 18-24 inches tall and as wide and is dense with salmon pink blooms in September. Also drought-tolerant and deer-resistant, it's a winner all the way.
