Panicle Hydrangea (Hydrangea Paniculata ‘Smnhprzep’ Zinfin Doll)

Panicle Hydrangea

Features and Characteristics

Hydrangea paniculata, commonly called panicle hydrangea, is a vigorous, upright, rapid-growing, somewhat coarsely textured, deciduous shrub that is native to China and Japan. It typically grows to 8-15’ (less frequently to 25’) tall, and features oval to ovate dark green leaves and upright, sharply-pointed, conical, terminal flower panicles (to 6-8” long) containing both fertile and sterile flowers (mostly non-showy fertile flowers) that bloom from mid-summer into fall.

The genus name Hydrangea comes from hydor meaning “water” and aggeion meaning “vessel”, in reference to the cup-like capsular fruit.

The specific epithet paniculata refers to the arrangement of the flowers in panicles.

‘SMNHPRZEP’ is an upright to semi-spreading selection of panicle hydrangea that features cone-shaped inflorescences made up of white, sterile flowers that mature to deep red-pink. The terminal panicles reach around 6″ long and are held on sturdy stalks, making them excellent for use in fresh and dried arrangements. Mature plants will reach up to 8′ tall with a 6′ spread. Often sold in nurseries under the trade name ZINFIN DOLL. This plant is protected by patent number PP2695

Care and Maintenance

Best grown in organically rich, medium moisture, well-drained soils in full sun to part shade. Can be trained as a small single trunk tree, but is best grown as a large, multi-stemmed shrub. May display best shrub form if regularly pruned to a height of 6-10’ tall. This is one of the most winter hardy of the hydrangeas. It thrives in urban conditions. Bloom occurs on current season’s growth, so prune as needed in late winter to early spring.

Larger flower panicles can be obtained by thinning the plants to 5-10 primary shoots. In full bloom, the weight of the flower panicles will typically cause the branches to arch downward.
