A bold and audacious tree-form shrub that produces endless reams of massive and dense conical flower clusters at the ends of the branches, probably the fullest flower heads of the panicle hydrangeas; long-lasting blooms are white and later turn rosy-red
Tree Form Pee Gee Hydrangea features bold conical white flowers at the ends of the branches from mid summer to late fall. The flowers are excellent for cutting. It has green deciduous foliage. The pointy leaves do not develop any appreciable fall colour.
Tree Form Pee Gee Hydrangea is a deciduous shrub, selected and trained to grow in a small tree-like form with the primary plant grafted high atop a standard. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.
This is a high maintenance shrub that will require regular care and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.
Tree Form Pee Gee Hydrangea is recommended for the following landscape applications;
- General Garden Use
- Container Planting
Planting & Growing
Tree Form Pee Gee Hydrangea will grow to be about 6 feet tall at maturity, with a spread of 6 feet. It tends to be a little leggy, with a typical clearance of 3 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.
This shrub performs well in both full sun and full shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
Tree Form Pee Gee Hydrangea is a fine choice for the yard, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
