PeeGee Hydrangea (H. paniculata ‘Grandiflora’) plants are flowering deciduous shrubs. You will also hear “tree hydrangea” (or “hydrangea tree”) in reference to this plant, because it can be pruned so as to have a single trunk (that is, you can train it to be a “standard”) or just a few large trunks. Pruning it in this fashion allows you to accentuate a tree-like canopy. PeeGee hydrangeas will grow anywhere from 10 to 25 feet in height. Exact height and spread will depend on pruning and growing conditions. These are fast-growing shrubs, able to put on 2 feet in height some years under the best of conditions. They come into flower in mid-to-late summer.
Grow PeeGee hydrangeas in full sun in order for them to flower best. The soil should be well-drained and enriched by organic matter. A soil pH that is slightly acidic is preferred.
Full sun is recommend.
