Floribunda Roses are a classification of roses that are upright bushes that are remontant (multiple bloomers), with cluster-flowering as opposed to single flowering of the hybrid teas. Floribundas are the result of crossing Multiflora roses (Rosa rugosa) which are also called Polyanthas, with Hybrid Teas. Much of this work was done by P.T. Poulsen.
Poulsen was looking for roses that would thrive in the Scandinavian climate. Floribundas retain much of the hardiness, freedom and continuity of flower of the Polyanthas. Although Floribunda's have a much a smaller flower, they do have a better continuity of bloom than hybrid teas (HT). The flowers tend to be technically less perfect than those of HTs and may be single, semi-double, or fully double. Fewer floribundas are scented.
However, many rosarians feel that it was Eugene Boerner who developed the floribunda rose into what it is today. Boerner developed numerous floribundas during his 45-year career at Jackson & Perkins beginning in 1920, which lead to his becoming known as "Papa Floribunda." During that time he developed such floribundas as Vogue, Ivory Fashion, Apricot Nectar, and Gene Boerner (which was introduced posthumously). Gene Boerner hybridized more than 60 floribunda roses in his lifetime— 11 were given the All-America Rose Selections (AARS) award.
Floribunda roses are ideal for borders or containers. They provide an almost constant show of color, and bloom more freely than hybrid teas and grandifloras. They are lower growing and hardy in zones 4-9 (with proper protection). Floribunda roses are excellent for companion planting.
Beginning of each new season, prune floribundas back by 1/3 to outward-facing buds. Clean out the centers, remove dead and cluttered canes, and in beds of floribundas, shape the bushes to an even height for best presentation.
Floribundas need plenty of feeding. They need extra nutrients to keep their abundant bloom production in high gear. Keep them on a regular feeding schedule. They will also appreciate a heavy layer of mulch.
Floribundas take a minimum of 3 years to reach maturity. After establishing a good root system, they'll produce spectacular showy sprays or blooms. Floribundas can be grown either in the ground or large pots. With proper care, regular feeding, and annual pruning, floribundas will more than earn their space your garden.
