A large growing improved rockrose with huge white flowers with a large red basal blotch on each petal. Deep green foliage takes on maroon tints in cold weather. To 4′ tall and 8′ wide forming a dense outline. Blooms May to July in a daily procession of flowers. Each blossom is 3″ across. Excellent cold hardiness to 5ºF or lower. Grows quickly in average, well drained soil Avoid overly enriched sites which will decrease cold hardiness and lead to rank growth. Lean conditions produce the most dense and cold hardy shrub. Great for rough areas in the back ground. Completely drought adapted- no summer water required. Give it room to spread.
