The Pee Gee Hydrangea (Hydrangea paniculata ‘Grandiflora’), is a hardy, popular medium sized shrub that flowers in late summer. It prefers moist conditions and should not be allowed to dry out. Place a thick layer of mulch around the base of the shrub to protect it during the winter. Pee Gee’s have woody stems, so they don’t need to be cut back, but if desired, prune in late winter/early spring once threat of extreme cold is passed. Pee Gee’s bloom on new growth, so you won’t be cutting off any flowers buds in the spring.
Full sun to part sun. Zone 3, plant in sheltered location with lots of snow cover.
