Overview
Rosa (Floribunda Group) includes floribunda roses (cluster-flowered roses), compact mounding deciduous shrubs growing 2-4 feet (0.6-1.2 m) tall and 2-3 feet (0.6-0.9 m) wide. Flowers 2-3 inches (5-7 cm) in white, pink, red, yellow, orange, apricot, lavender, or bicolor — single, semi-double, or double — borne in clusters (sprays) of 3-15 per stem. Repeat-blooming from May through October (20 weeks). Moderately fragrant (cultivar-dependent). Glossy dark green pinnately compound leaves with 5-7 serrated leaflets. In Rosaceae. Developed by crossing hybrid teas with polyantha roses in the early 20th century. The cluster habit (multiple flowers per stem) distinguishes floribundas from hybrid teas (one flower per stem). Black spot (Diplocarpon rosae), powdery mildew, and Japanese beetles are the primary pest and disease concerns — this disease susceptibility and the resulting need for regular monitoring or spraying is the primary maintenance limitation. Disease-resistant cultivars reduce spray requirements: 'Iceberg' (white), 'Julia Child' (butter-yellow), 'Sexy Rexy' (pink). Not drought-tolerant — requires 1 inch (2.5 cm) of water per week. Winter protection (mounding mulch over the graft union) needed in zones 5-6. Deer browse. Non-toxic. Zones 5-9. Full sun. Growth rate is moderate.
Native Range
Complex hybrid origin — developed in Europe and North America by crossing hybrid teas with polyantha roses in the early 20th century.Suggested Uses
Grown in rose beds, borders, mass plantings, and in containers of at least 10 gallons (38 L), spaced 2-3 feet (0.6-0.9 m). Continuous cluster bloom May-October. Disease-resistant cultivars reduce spray needs. High maintenance. Non-toxic. Zones 5-9.How to Identify

Care & Maintenance
Care Guide
Full sun (6+ hours). Well-drained soil pH 6.0-7.0. Not drought-tolerant — 1 inch (2.5 cm) water per week. Black spot and powdery mildew — choose disease-resistant cultivars. Japanese beetles in zones 5-7. Deadhead spent clusters. Winter protection (mulch over graft union) in zones 5-6. Prune in late winter (February-March). High maintenance. Deer browse. Non-toxic. Zones 5-9.Pruning
Prune in late winter (February-March) before new growth. Remove dead, damaged, and thin (pencil-diameter or smaller) canes. Shorten remaining canes to 12-18 inches (30-45 cm). Cut to an outward-facing bud. Open the center for air circulation (reduces disease). Remove suckers from below the graft union.Pruning Schedule
