The Rate Of Growth Of Panicle Hydrangeas?

Panicle hydrangeas, also known as peegee hydrangeas, hardy hydrangeas, and Limelight hydrangeas, are popular for their beauty and adaptability. They grow across North America, from chilly USDA zone 3 to balmy USDA zone 8, making them suitable for planting in various regions. They don’t require fertilizer but can grow faster if given it, especially in areas with acidic or alkaline pH levels that can cause nutrient deficiencies.

Panicle hydrangeas bloom on the current season’s growth and can be pruned back by up to one-third of their size in early spring. They are fast-growing, with up to 3 feet of new growth per season, and the wild-type species can reach 16 feet (5 m). Gardeners often cut this shrub back to 6 to 8 feet.

Panicle hydrangeas can be grown in containers for at least a couple of years, using a weather-proof container with drainage holes at least 16. They root quickly, and within two to three weeks, cuttings should resist a gentle pull, indicating fresh roots have pushed into the medium. Rooted plants can be kept indoors or in a container.

Tree hydrangeas, or panicle hydrangeas, are fast-growing flowering shrubs with an upright growth habit and cone-shaped flower panicles. Quick Fire® hydrangea is a large, multi-stemmed, woody, deciduous shrub or small tree that is rapid-growing and coarsely textured. It blooms about a month before any other panicle hydrangea variety, usually by the 4th of July in West Michigan trials. In gardens on Cape Cod, panicle hydrangeas come into bloom in July (early or late according to variety) and remain in flower until October.
