Bigleaf Hydrangea 'Paris Rapa' (Cityline® Paris): Compact Rebloomer for Urban Gardens

Cityline® Paris ('Paris Rapa'): Big Blooms, Small Footprint

Hydrangea macrophylla 'Paris Rapa' (PP10906), marketed as Cityline® Paris, is a breakthrough compact cultivar from the Cityline® series, bred by Rampp and introduced in 1999. It was developed specifically for urban gardens, containers, and small spaces—delivering full-sized mophead flowers on a dwarf, sturdy plant.

Urban-Friendly Form

Cityline® Paris forms a neat, rounded mound just 1–2 feet tall and wide—truly dwarf. Despite its small stature, it produces surprisingly large mophead inflorescences, 5–6 inches across, with deep pink to violet-blue flowers (pH dependent). The sterile florets are broad and numerous, creating dense, symmetrical globes. Strong stems hold the flowers upright without flopping.

Foliage is dark green, glossy, and disease-resistant. The compact habit requires no pruning to maintain shape.

Container Superstar

Bred for container culture, 'Paris Rapa' thrives in pots on balconies, patios, and rooftops. It also excels in small garden beds, foundation plantings, and as a low edging. Standard macrophylla culture: morning sun or bright shade, consistent moisture, well-drained potting mix or garden soil. Hardy in USDA zones 5–9 (more cold-tolerant in ground than in pots). Blooms on old wood.
