Culture

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.

Noteworthy 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.

'Piihp-1' is a compact selection of panicle hydrangea that features white blooms held on sturdy, upright stalks. The cone-shaped, terminal inflorescences reach 5" long and are made up of showy, white sterile florets and small, white fertile florets. The sterile florets age from white to green as the season progresses. Mature plants will reach up to 4' tall with a similar spread and take on a rounded habit. Commonly sold in nurseries and garden centers under the name BABY LACE. Plant patent number PP23387 applies to this cultivar.

Problems

Some susceptibility to bud blight, bacterial wilt, leaf spot, rust and mildew. Aphids and mites are occasional visitors.

Uses
