General Hydrangea paniculata Info:
Panicle Hydrangea is the most cold hardy Hydrangea we can grow. Its large and showy bloom comes at a welcome time of the year, beginning in mid to late summer and lasting well into fall. This fast growing species can become quite large with some specimens here in Indiana reaching over 12 ft. in height. They are easily kept smaller by occasional pruning or if you want to go to the other extreme you can fashion them into small trees.

This Variety:
'Pink Diamond' is a refined 1997 selection from the famous Kalmthout Arboretum in Antwerp, Belgium. It is somewhat smaller growing than the species. The large panicle inflorescences emerge pure white beginning in mid-July. As the flowers age, the showy flower sepals turn a rich pink color.




 
Ornamental Characteristics: Huge flower inflorescences are up to 12" long and 8" wide. The panicles begin to emerge in mid-July and are initially pure white. The showy sepals age to rich pink. Flowers last well into fall.
Habit & Growth Rate: Fast growing to 8 to 10 ft. tall and 6 to 8 ft. wide. Can be kept smaller by hard pruning or can be trained into a tree form.

Culture: Very adaptable plant that's easy to grow in average garden soil in sun or part shade. Flowers on new wood so best pruned in winter or early spring. Will take hard pruning well.
