How tall does hydrangea Nikko Blue get?

Hydrangea Nikko Blue, also known as the hortensia or mophead hydrangea, is a beautiful deciduous shrub that can add a stunning touch to any garden or landscape. One of the first things you may want to know about this hydrangea variety is its height. On average, ‘Nikko Blue’ hydrangea typically grows to be around 4-6 feet tall. However, it is important to note that the ultimate height can vary depending on various factors such as growing conditions, pruning, and the overall health of the plant.

When it comes to the growth habit of ‘Nikko Blue,’ it tends to have a rounded shape, adding a soft and elegant appeal to the landscape. The foliage is lush and green, with large, glossy leaves that provide a beautiful backdrop to the showy flowers. The flowers of ‘Nikko Blue’ are what truly steal the show. They are large, round clusters of sterile florets, arranged in a globular or “mophead”-like panicle. The color of the flowers is a stunning blue, which can vary in intensity depending on the soil pH and the availability of aluminum.

In terms of care and maintenance, ‘Nikko Blue’ hydrangea is relatively easy to grow, making it a popular choice among gardeners. It prefers well-drained soil, enriched with organic matter, and a location with partial shade. However, it can tolerate full sun in cooler climates or with sufficient moisture. Regular watering is essential, especially during dry periods, to keep the soil consistently moist but not waterlogged. Adding a layer of mulch around the base of the plant can help retain moisture and regulate soil temperature.

Pruning is another important aspect to consider when it comes to managing the height and shape of your ‘Nikko Blue’ hydrangea. Pruning should be done in late winter or early spring before new growth begins. Generally, it is recommended to prune back the stems to about one-third of their height to encourage vigorous growth and abundant blooms. However, if you prefer a more compact size for your ‘Nikko Blue,’ you can prune it more heavily.

It is worth mentioning that the height and overall size of ‘Nikko Blue’ hydrangea can also be influenced by the age of the plant. Younger plants may take some time to reach their full height potential, while older, established shrubs may have a more robust growth habit. Additionally, proper fertilization can also contribute to healthy growth and size. Using a balanced fertilizer formulated specifically for hydrangeas can provide the necessary nutrients for optimal growth.

‘Nikko Blue’ hydrangea is a stunning deciduous shrub that typically grows to be around 4-6 feet tall. Its rounded habit, lush green foliage, and showy blue flowers make it a popular choice among gardeners. By providing the right growing conditions, regular watering, and appropriate pruning, you can help ensure that your ‘Nikko Blue’ hydrangea reaches its full height potential and adds a beautiful touch to your garden or landscape.
