Overview
Floribunda roses are a class of Rosa hybrids reaching 2-4 feet (0.6-1.2 m) tall with a spread of 2-3 feet (0.6-0.9 m), developed in the early 20th century by crossing hybrid tea roses with polyantha roses. The name means 'many-flowered,' and the class is characterized by flowers produced in large clusters (sprays) of 3-15 or more blooms per stem, providing continuous mass color. Individual flowers range from single (5 petals) through semi-double to double (25-30 petals), 2-3.5 inches (5-9 cm) across — smaller than hybrid teas but far more numerous per stem. Flower forms are typically less formal than hybrid teas, with a more open, cupped, or rosette shape. Available in the full range of rose colors: white, pink, red, yellow, orange, apricot, lavender, and bicolors. Many are fragrant. Leaves are alternate, pinnately compound, with 5-7 glossy, serrate leaflets. Growth habit is bushy, compact, and well-branched. Repeat-blooming from late May through October in the Pacific Northwest. Generally more disease-resistant and cold-hardy than hybrid teas. First officially recognized as a class by the American Rose Society in 1952. In the Pacific Northwest, black spot, powdery mildew, and rust are persistent concerns; disease-resistant cultivars are recommended.
Native Range
Complex hybrid origin, developed in the early 20th century primarily from crosses between hybrid tea roses and polyantha roses. Key early breeders include Dines Poulsen (Denmark) and Eugene Boerner (USA). Parent species include Rosa chinensis, Rosa multiflora, Rosa gallica, and others.Suggested Uses
Planted in rose beds, mixed borders, foundation plantings, and mass plantings for continuous color, spaced 2-3 feet (0.6-0.9 m) apart. The cluster flowering habit provides more landscape color per plant than hybrid teas. Disease-resistant cultivars for the Pacific Northwest include 'Iceberg' (white), 'Julia Child' (yellow, fragrant), and Knock Out series (various colors). Suitable for large containers (minimum 10-gallon).How to Identify

Bloom Information
Repeat-blooming from late May through October in the Pacific Northwest, with heaviest flushes in June and September. Deadheading spent clusters promotes continuous flowering. Each cluster opens over 1-2 weeks, providing extended color from each stem.Detailed Descriptions

Care & Maintenance
Care Guide
Water deeply 1-2 inches (2.5-5 cm) per week during the growing season, applied at the base to keep foliage dry. Plant in full sun with at least 6 hours of direct light and good air circulation. Requires fertile, well-drained soil amended with compost. Mulch 2-3 inches (5-8 cm). Select disease-resistant cultivars for the Pacific Northwest. Fertilize monthly May through August; stop by mid-August. Aphids are common in spring; manage with strong water spray or insecticidal soap.Pruning
Prune in late winter (February through early March) as buds begin to swell. Remove dead, damaged, and diseased canes. Remove thin, twiggy growth. Reduce remaining canes by one-third to one-half, cutting to an outward-facing bud. Retain 5-8 strong canes forming a vase-shaped framework. Deadhead spent flower clusters during the growing season.Pruning Schedule
