Nikko Blue Hydrangea 12-18" Description

Nikko Blue Hydrangea 12-18" - Hydrangea macrophylla 

Nikko Blue Hydrangea 12-18" blooms around early summer lasting approximately two months, and is highly floriferous, meaning it keeps producing fresh flower stalks during the summertime. It is a fast-growing plant featuring giant, spherical flower heads that bloom in a vibrant, sky blue color over the summer.

The vivid flowers persist for months, adding texture to the landscape far into fall, even after their color has begun to fade. Its foliage is moderate greenish with gigantic, glossy, serrated leaves. 

These leaves are 8 inches or more in length and cover the plant straight down to the soil surface, forming a circular mound that helps conceal the land underneath it and inhibit the growth of weeds. It is covered in gigantic balls of rich-blue blooms during the summer that lingers for weeks. Even though they finally fade to a light brown hue, they remain on the plants until the end of the season, offering them an aesthetically pleasing aspect.

Nikko Blue Hydrangea 12-18" and its striking flash of color 

This hue of blue is scarce among various house garden plants, but this shrub produces a deep indigo shade that is sure to become the central feature of your landscape. For even more blue magnificence in your home during summer, you may welcome stunning fresh flower arrangements of these plants indoors, or you can use dried flowers to create a breathtaking aesthetic showcase.

 In bloom from late June to September, this award-winning plant attracts attention with its vast, 6-inch pom-pom-like petals set amidst emerald green leaves that create an ethereal quilt-like appearance.

These leaves feature light green veins that are deeply embedded and form a carved, swirl-like pattern on the surface of the leaves. This fast-growing plant will have hit its maximum size within two or three years, making it a perfect remedy for a rapidly expanding privacy screen. This beautiful shrub thrives in shaded regions. It creates a thick clump of huge leaves adorned with giant circular heads of stunning blue flowers that bloom throughout the season, the summertime.

The color of the blooms will also be more vibrant in the shade. They expand to a height of about 6 feet and a spread of about the same. By pruning a bit deeper every spring, you may keep the height under control and direct the size of your plants. The longer you keep it in the shade, the shorter the plant will remain. In some dire situations, it might even remain small enough to mimic the size of a big perennial.

Growing condition

They prefer soil that is moist, fertile, and also well-draining. As with several other ornamental plants, this plan will also suffer in overly wet or soggy soil. The pH level of the soil combination in which you want to plant your shrub is one of the most crucial factors to consider. It is relatively simple to alter the color of your hydrangea shrub to either blue or pink by changing the pH level of your soil. Acidic soils would produce blue blossoms, whereas alkaline soils would produce pink blossoms on these shrubs' branches. You can mix aluminum sulfate into the soil if you want to get a bluer shade of the flowers, or you may add lime to the soil if you get a more pink hue.


This plant caters to all sorts of applications, from foundation to container plantings. It is a magnificent shrub to employ as an ornamental specimen or border plant in semi-shaded settings. It develops to a size that allows it to offer dependable foundation planting across walls and fences and for partitioning and screening purposes.

It looks stunning whether you use it as an accent plant among lighter green plants or even if you mass plant them to increase the visual impact of their beautiful blossoms in massive fields. It is prized for its spectacular, profuse, and beautiful flower clusters. It bears lovely deep green foliage on a robustly branched, mounded structure and develops on old wood.

Purple, pink, and white color schemes are ideal for using this plant as a focal point in your cool-toned landscape. It is efficient as a hedge and produces beautiful cut flowers as well. You may incorporate it as a single plant within any shaded border. However, a vast territory of these shrubs, planted across a shaded wall or driveway, next to trees, or beside a shady pathway, is a lovely and straightforward method to create an environment of true serenity and tranquility.

    l don't believe the plant was the height advertised, but it was alive and appeared healthy. I only got the plant 3 days ago and planted it the same day. Hard to say more.
