Plant Description
Panicle hydrangea, scientifically known as Hydrangea paniculata, is a deciduous shrub that belongs to the Hydrangeaceae family. Originating from East Asia, particularly China and Japan, this plant is characterized by its large, pyramid-shaped flower clusters, or panicles, which typically emerge in mid to late summer. The flowers initially appear creamy-white and gradually transform to shades of pink and eventually deep russet as the season progresses. The stunning blooms often persist well into the fall, adding an appealing aesthetic to the garden even during the latter part of the year.
With a strong, but graceful, upright growth habit, panicle hydrangeas can reach heights of 6 to 10 feet, making them an ideal choice for creating hedges, screens, or standalone ornamental specimens. The foliage of Hydrangea paniculata consists of dark green, ovate leaves that provide an attractive backdrop to the magnificent floral display.
