The Story
Plant Bio
A class of hybrid roses resulting from crosses between Hybrid Tea and Floribunda roses. They are vigorous, upright deciduous shrubs that typically produce large, elegant, hybrid-tea-style flowers in small clusters on long stems. Combines the characteristics of Hybrid Tea roses (large, shapely blooms on long stems) with the Floribunda habit of bearing flowers in clusters and blooming prolifically throughout the season. Taller than most Hybrid Teas and Floribundas.
