More information
The rose currently known as Max Graf is considered an older cultivar that received a new name after being found by a worker at Bowditch Nursery in Connecticut. It is a hybrid of Rosa wichurana and Rosa rugosa, with dark pink flowers that fade to pink and a prominent cluster of pale yellow stamens. Blooming is relatively late, but the flower clusters are large. The shoots are creeping, and the foliage is dark green and glossy. The cultivar roots readily where shoots touch the ground. Shoots are densely set with sharp brown prickles. It is widely used as a groundcover rose; it does not suppress weeds, and the prickles make weeding difficult. Very winter-hardy, with strong resistance to black spot; also grown as a pleached rose.
Max Graf’s pink flowers appear in large clusters relatively late, when many other roses have already completed their first bloom. It is widely used as a low-maintenance groundcover along motorways and in urban landscaping, where it tolerates harsh conditions. The large, dark green, glossy foliage serves as a backdrop for other plantings.
