Winter Sunset shrub rose (Rosa 'Winter Sunset') produces orange buds that open to double golden-yellow petals, shading to orange at the center of the flower. This is another of the really tough shrub roses to be released by Iowan and noted breeder Griffith Buck. It has good resistance to fungus and mildew on a bushy habit that reaches 4 feet high by 3 feet wide. This color range is more typically found in hybrid tea roses and is a real treat for USDA Zone 5 gardeners (like those in the Chicago area) who prefer not to heavily mulch their roses at the onset of winter.
