Hybrid origin (compact garden hybrid; pompon-flowered)
Overview
Philadelphus 'Snowbelle' is a deciduous shrub reaching 3-4 feet (0.9-1.2 m) tall with a spread of 3-4 feet (0.9-1.2 m) and a compact, rounded, dense habit. This hybrid mock orange produces fully double, white, ball-shaped flowers 1-1.5 inches (2.5-4 cm) across, moderately fragrant, in May-June. The fully double flowers are packed with petals in a rounded, pompon-like form—more uniformly double than 'Goose Creek'. The opposite, ovate leaves are 1-2.5 inches (2.5-6 cm) long, medium green. Growth rate is moderate. Hardy to zone 4. The compact, rounded habit and the uniformly double pompon flowers make this a tidy garden shrub. Intermediate in size between the dwarf 'Snow Dwarf' and the medium 'Galahad'.
