Bright-red double flowers up to 4 inches in diameter are features of Rosa ‘Hi, Neighbor’, a hardy, disease-resistant grandiflora rose created by the Buck Rose breeding program in Iowa. Glossy green foliage covers this shrub that can reach 4 feet by 4 feet in size. It is very hardy, with survival documented at minus 30 degrees Fahrenheit. This rose features a light scent, but rarely produces fruit. Grow it in full sun and prune to shape; remove deadwood in early spring, after the danger of very cold weather has passed. Treat cutting implements with a disinfectant to avoid spreading viruses between plants.
