Hydrangea paniculata, commonly called panicle hydrangea, is a vigorous, upright, rapid growing, deciduous shrub that is native to Japan and China. It grows to 3-5 meter high, and features oval to ovate dark green leaves and upright, sharply-pointed, conical, terminal flower panicles containing both fertile and sterile flowers that bloom from mid-summer into autumn. 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. [Misouri Botanical Garden]
