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.

Genus name comes from hydor meaning water and aggeion meaning vessel in reference to the cup-like capsular fruit.

Specific epithet is in reference to the flowers being arranged in panicles.

'Ilvomindy', commonly sold under the trade name of MEGA MINDY, was bred by Johan Van Huylenbroeck of Melle, Belgium from an open pollination of Hydrangea paniculata 'Pink Diamond' as the female parent and an unknown Hydrangea paniculata as the male parent. MEGA MINDY was named for a Flemish children's television character who wears a pinkish red uniform. It is a compact, mounded shrub with large cone-shaped panicles of white flowers that age to pinkish red and are held upright on strong stems. MEGA MINDY grows 4 to 5 ft. tall and 4 to 6 ft. wide.
