For example, Othello is a carmen red rose with little or no disease, and it produces a steady stream of red roses from June to frost. Climbing Roses Climber is a general term for roses that produce long, vigorous canes that cannot support their own weight. They are usually trained on trellises, fences, walls, posts, or arbors. Many of these varieties can be used as ground cover when no supporting structure is used. This category is usually divided into several groups, although many individual roses may qualify for one or more classifications.
Ramblers are one the most vigorous of all the climbing roses.
Some canes may produce as much as 20 feet of new growth each season. The small flowers are borne in clusters in the spring on the previous season s growth. Unfortunately, many of these cultivars are subject to severe mildew damage. Most are hardy and require little or no winter protection. Seven Sisters is an old, mildew-prone, pink flowering rambler found on many farm fences in southern Oklahoma.
