Captain Samuel Holland
Rosa rugosa 'Captain Samuel Holland'

Large spreading shrub rose when allowed to grow unsupported but can also be treated as a climber due to the long trailing canes. Glossy foliage. Red double flowers 3 inches wide (petal count 15-25) and has a slight fragrance. 
Full sun, well-drained soil. Prune by the renewal method removing one-third of the oldest canes at soil line in the spring as needed to keep the shrub open and allow for new cane production. Prune the stem back to a branch angle (a process called heading back) as needed to reduce width and height.
