With its deep purple-black leaves and brilliant summer blooms, ‘Bishop of Llandaff’ is a fine addition to the sunny bed or border. The 4- to 6-inch-round red-petaled flowers have deep purple and yellow centers, which are set off nicely by the plant’s dark foliage. Use this long-stemmed cultivar in cut-flower arrangements. -Gerald Gibbens, Regional Picks: Northwest, Fine Gardening issue#120
