White Knock Out® Rose

White Knock Out® Rose produces a steady display of clean white flowers from spring until frost. The blooms stand out against very dark matte-green foliage, including young leaves that can emerge nearly black. Its compact, rounded habit fits easily into foundation beds, sunny borders, low hedges, mass plantings, and light-colored evening gardens. Plant it in full sun and well-drained soil, and water regularly while establishing. A light floral fragrance and low-maintenance repeat bloom make it an easy landscape rose.
