Plant Profile: Hydrangea paniculata 'Grandiflora'

Peegee hydrangea, a sizable shrub or small tree native to Asia, thrives best in organically rich, moist, and well-drained soils, ideally situated in full sun to partial shade. This robust plant can grow up to 25 feet tall, although regular pruning can help maintain a more manageable height and shape. Known for its hardiness, it adapts well to urban environments. Pruning should be done in late winter since its flowers develop on new growth from the current year. However, be aware that deer may browse on it.

The large, creamy white flower clusters can be encouraged to grow even larger by limiting the shrub to 6 to 10 main stems. The weight of the blooms often causes the branches to arch gracefully. This hydrangea can be used as a standout specimen, in hedges, or grouped with other plants.

It is generally resistant to pests and diseases, though issues such as leaf spot, powdery mildew, scales, and mites can occasionally arise.

**Quick Identification Tips:**
This deciduous plant typically grows as a large upright shrub or small tree, reaching heights and widths of 10 to 20 feet, though it often remains under 10 feet. Its branches have a semi-arching form.

For optimal growth, it prefers organically rich, moderately moist, well-drained soil in partial shade. It is salt-tolerant but struggles in hot, dry conditions and is easy to transplant.

With rapid growth and a somewhat coarse texture, it is well-suited for mass plantings, mixed shrub borders, open woodland gardens, or as a specimen or accent plant in hedges. It produces striking blooms in late summer when few other plants are flowering and faces minimal pest or disease challenges. Since it flowers on new wood, it can be pruned in winter or early spring, with the largest flower clusters appearing on plants pruned to 5 to 10 primary branches.
