Floribundas were bred from the hybrid teas and polyanthas. Grandifloras, one of the newer kinds of roses, resulted from crossing hybrid teas with floribundas. The climbing and rambler roses can be trained on trellises and fences. Others creep over the ground and may cover steep banks. Some climbers have large flowers, but true ramblers have clusters of small flowers.
Climbers have to be hardy.
Those with the small flowers are usually the hardiest. Another important group is the shrub roses. They usually have fragrant flowers. The sweetbrier and its cultivated forms are tall, graceful bushes, with fragrant leaves. Some have flowers no larger than a nickel.
