Top Gun Shrub Rose produces clusters of semi-double, rich red flowers and dark green foliage—and it repeat blooms frequently. It also exhibits excellent natural resistance to powdery mildew, downy mildew, rust, black spot and even rose rosette disease. This striking variety has excellent resistance to most major rose diseases, including the devastating rose rosette disease, which puts Top Gun at the top of its class. In several trials throughout the eastern U.S., it was untouched by RRD, while most other varieties showed symptoms of infection.
