Blue Hydrangea Shrub

Blue Hydrangea Shrub

Blue hydrangeas are your go-to choice for an elegant flowering shrub. When shopping for a shrub with old-fashioned charm, this is one of the most elegant. They are easy to cultivate, grow in almost any soil, and produce abundant dinnerplate-size blue snowball blooms throughout the warm season and into autumn. They are unique plants because you can control their color. However, not all hydrangeas can withstand color adjustments. To increase the color intensity of your shrubs, lower your soil's pH. By reducing the soil’s pH, hydrangeas can absorb sufficient aluminum, giving them a beautiful blue color.

Landscape Enhancement: 

Perfect for creating striking garden features such as hedges or focal points. Its dramatic blooms and lush foliage can transform and elevate any landscape design.

Cut Flower Potential: 

Blue Hydrangea makes stunning cut flowers for indoor arrangements. Its elegant blooms bring a touch of garden beauty inside your home, perfect for fresh floral displays.

Height and Coverage: 

Blue Hydrangea can be used to create height and depth in your garden, with some varieties climbing up to 50 feet, making them perfect for covering fences or scaling trees.

Frequently Asked Questions

Do blue hydrangeas like sun or shade?

Blue hydrangeas grow best in partial sun with some afternoon shade. Morning sunlight helps them bloom richly, while light shade protects their flowers from heat. This balance keeps the plant healthy and full of vibrant color.
How do I get my hydrangeas to be blue?

To keep hydrangeas blue, plant them in acidic soil with a pH below 6. Adding aluminum sulfate or organic matter like pine needles helps maintain their color. With the right soil balance, their blooms stay beautifully blue all season.
How tall do blue hydrangeas get?

Blue hydrangeas typically grow 3 to 6 feet tall, forming full, rounded shrubs. Their lush blooms create a stunning display in any garden. With sunlight and good soil, they grow strong and flower abundantly each year.

I had doubts when I first opened the box. Packaged well. After planting them after two weeks they came to life and are flourishing quite well. They are very healthy and now branching out vividly. Thank you!

Giant Chicory!

I purchased a selection of blue plants. I planted the bare roots in a large planter I call the nursery. I wait until they are adapting to their new environment. When they start growing about three inches, I transplant to a larger pot, then to their permanent location in my garden. One grew to four feet. Others are 1- 2 feet! I can see buds sprouting and can’t wait until they bloom. I did have to cut the 4ft one down to 2 ft so it would get fuller.

My favorite spring flower

My absolute favorite spring flower. I’ve bought several over the years. Sometimes I’ve found they might not come up until the second year but most from this nursery come in the next spring.

I just want to say I would give 5 star satisfaction but my trees are just now in the ground. My shipment arrived fast and in great condition. The bare root trees already trimmed to perfection. I am so pleased. Been in the ground a week and already have green growth.
