Plant Common Name

Panicle Hydrangea, Paniculate Hydrangea

General Description

One of the most beloved of the large ornamental hydrangeas, panicle hydrangea is named for its huge pyramidal clusters, or panicles, of showy ivory flowers. This large deciduous shrub can be trained to a tree-like form and is native to China and Japan. Mature specimens on single standards have long branches that arch downward—giving the small trees a timeless elegant look in the landscape.

Large green leaves line the stems in spring and darken with age. These turn less than showy shades of yellow in fall. In mid to late summer large panicles of flowers appear. These are covered with small inconspicuous fertile flowers and showy, sterile, four-sepaled flowers that are flattened and papery. The sterile blooms are initially ivory but turn soft dusty rose or pink as they age. In fall they dry to tan and persist into winter. Most cultivars have a higher number of showy, sterile flowers.

Panicle hydrangea is best placed in a site with full to partial sun and fertile soil with average moisture and drainage. Established specimens can tolerate urban conditions and limited drought. The fantastic summer blooms of this large shrub make it ideal as a backdrop for mixed borders and large landscape plantings. Its flowers are also great for arrangements, fresh or dried.
