Floribunda roses blossom almost continuously except for a short winter dormant period in Zones 9 and 10, and from spring until frost in Zones 3-8. Combining the virtues of their parents--the hardy polyantha, with its clusters of small blossoms, and the showy hybrid tea rose, with its large blossoms on long stems--they produce clusters of moderately large blooms on fairly long stems, and are relatively hardy, most varieties surviving without winter protection in Zones 6-10.
Most varieties have elegant, high-centered, 2- to 4-inch blossoms, with long, pointed buds similar to those of hybrid teas. The blossoms are often heavily doubled, with up to 60 or more petals; there are also five-petaled single blossoms and semidoubles with fewer than 20 petals. Colors range from snowy white and cream to yellow, apricot, orange, coral, pink, red and lavender. Well-shaped bushes usually grow 2 to 3 feet tall with foliage similar to that of hybrid teas.
Floribundas make good hedges and can be massed in beds of their own or in front of taller roses. They provide constant color and good cut flowers.
