The individual blooms on climbing roses can be of a finer quality and larger than those of the bush form. Climbing roses whose names are not prefaced with ‘Climbing’ or 'Cl' are bred by crossing two roses. They generally have a heavy spring crop followed by a better repeat bloom and usually a good fall crop of blooms with a few exceptions. A few seedling Climbing roses bloom only once and are so noted. Some climbers will not bloom the first year as they need time to establish and develop height. Climbers bloom on old wood so many times, they will not bloom until the second year and beyond. Climbing roses are a diverse group with many different heritages, which makes this a wonderfully useful collection of roses. Large-flowered climbing roses differ from Ramblers in that they have fewer, yet larger blooms (4-6 inches in size) and are not quite as vigorous. Being so diverse, they vary in winter hardiness, generally climbing roses are hardy zones 5 or 6 through 10 except as unless noted.
