How big does a hydrangea bush get?

Hydrangea bushes can vary in size depending on the specific variety and growing conditions. Some hydrangeas are compact and can reach a height and width of only 2-3 feet (60-90cm), while others can grow much larger, reaching heights of up to 6-8 feet (1.8-2.4m) and spreading out to 4-6 feet (1.2-1.8m) wide.

One of the most popular and widely planted hydrangea varieties is the Bigleaf hydrangea (Hydrangea macrophylla). These bushes can grow up to 4-6 feet (1.2-1.8m) tall and wide, forming a rounded shape. They are known for their large, showy flowers that come in various colors, including pink, blue, purple, and white.

Another common hydrangea variety is the Oakleaf hydrangea (Hydrangea quercifolia). These bushes tend to be larger, reaching heights of 6-8 feet (1.8-2.4m) and spreading out to 4-6 feet (1.2-1.8m) wide. They have distinct oak-shaped leaves and produce cone-shaped clusters of white flowers that gradually fade to pink. Oakleaf hydrangeas are known for their beautiful fall foliage, adding vibrant colors to the landscape.

Panicle hydrangeas (Hydrangea paniculata) are another popular choice for gardeners. These bushes can grow even taller, reaching heights of 8-12 feet (2.4-3.7m) and spreading out to 6-10 feet (1.8-3m) wide. They have elongated, cone-shaped flower clusters that start off white and gradually turn pink or even deep red, providing a stunning display throughout the summer and into fall.

It’s important to note that these size ranges are general guidelines and can vary depending on the specific cultivar, growing conditions, and how well the hydrangea is cared for. Some varieties may have dwarf forms that stay smaller, while others may have larger growth habits. Additionally, pruning can also influence the size and shape of a hydrangea bush.

When planting hydrangeas, it’s important to consider their mature size and allow enough space for them to spread out. This will prevent overcrowding and ensure that each hydrangea has enough room to grow and thrive. In general, hydrangeas should be planted at least 5 feet (1.5m) apart to allow for proper air circulation and to prevent diseases.

To summarize, hydrangea bushes can vary in size, with some staying compact at around 2-3 feet (60-90cm) and others growing larger, reaching heights of 6-8 feet (1.8-2.4m) or even taller. It’s important to choose the right variety for your space and provide enough room for each hydrangea to grow and flourish.
