This characteristic varies, however. When fragrance is present, it is usually most intense in early morning before the fragrant oil evaporates from the base of the petals. Most hybrid teas are winter hardy in areas where winter temperatures only occasionally fall below O degrees F, but most cultivars differ in cold resistance. In regions where winters are more severe, all cultivars need some protection. Floribundas Floribunda roses usually bear their flowers in clusters, and the individual blooms of many cultivars closely resemble hybrid teas.
Some new cultivars tend to have single but smaller blooms than hybrid teas.
Floribundas are increasing in popularity, especially for use in bed plantings whem many blossoms are desired. Grandifloras Grandiflora roses are a cross between hybrid teas and floribundas. The flowers are somewhat smaller than those of hybrid teas. They can, however, be as tall as 24 inches. Polyanthas Flowers of polyantha roses are smaller than those of grandifloras, but are borne in large clusters.
