Nikko Blue hydrangeas add a big pop of color to any landscape

A few years ago I wanted something for my front yard that would fill in a space a large bush once called home. My yard was full of the colors green, red and yellow, but no blue. I needed blue, being a Kentucky Wildcats fan and all.  Anyway, I looked high and low for something that would bring blue to my yard. My quest ended with my purchase of a Nikko Blue hydrangea.

When I bought the hydrangea the blooms were pink, but the display showed me the color of the big blooms depends on the acidity level of the soil. In acidic soil, the Nikko Blue hydrangea would have deep blue flowers, while in alkaline soil, the blooms become more of a pink color. Since I wanted blue blooms, I needed to make sure my soil was acidic. So I bought some organic fertilizer for "acid loving plants". For organic fertilizer that will do the trick, you can buy something like Bradfield Organics® Acid Adoring 4-5-4 Natural Fertilizer.  After applying the fertilizer I just had to wait a few days and voila, my hydrangea blooms were blue.  Going forward I just had to apply the fertilizer once every month or two.

The Nikko Blue hydrangea is low maintenance, but there are a few things to note. The Nikko Blue hydrangea grows best in fertile, well-drained soils. They are not very drought tolerant, and should be watered regularly during dry periods. The Nikko Blue hydrangea prefers full sun, but should be given half shade in areas that have overly hot summers.

The Nikko Blue hydrangea shrubs grow from four to six feet tall, and have a mature spread of five to seven feet. Hardy in zones 5 to 9.  You can view the U.S. hardiness zone map here.  The Nikko Blue hydrangea have large bright green leaves and dramatic flower colors. The Nikko Blue hydrangea blooms on large buds formed on growth from the previous season. Because of this, any pruning should be done immediately after flowering.

The photo above was taken of my Nikko Blue hydrangea in 2009 as the blooms were just showing their color. It continued to bloom throughout the summer. The Nikko Blue hydrangea was a good purchase for me. They are sold at most nurseries and home improvement stores. I would definitely recommend the Nikko Blue hydrangea to anyone who wants a big pop of blue or even pink in their yard.

Like the two previous comments -- I love hydrangeas!  They seem to be pretty simple to plant since I see them sprouting up anywhere, but I've yet to try planting them myself.  Will definitely do when I have my own garden because they're such a pleasure to photograph :)  Thanks for the interesting tidbits on this gorgeous flower, Clay!

That's true. Hydrangeas are very photogenic no matter the color of the blooms. Good luck on your future hydrangeas.

I'm with you. I L-O-V-E hydrangeas. It was a great year for hydrangeas in the Northeat in 2009. Definitely one of the prettiest plants around.

True. It was a great year for hydrangeas here in Kentucky as well. A whole lotta blue, pink and white to see.

Thanks for the review. I love hydrangea. I wanted to plant some in our front yard, but I wasn't sure if it would like the full sun. But it sounds like it might handle it ok.

Yep, hydrangeas do like the sun. I hope you get your hydrangea.

Feel Like A Change? Change the Color!
When I first saw Blue Hydrangeas at Home Depot, I was immediately impressed with the large colorful flowers.  I had a wall on the side of my house that I wanted to cover with some big splashes of color.  These bushes grow fairly large, so I only needed to buy two to cover the area I needed covered.  Instead of buying the more mature plants from Home Depot, I bought smaller plants from the Farmer's Market.      After the first year of growing, my small …

I love all my garden, I have some hydrangea mophead and nikko blue; one from home depot or big box are NOT organic and always die. support your local organic nursery. I plant a lot of milkweed to save butterflies as well as a lot of butterfly bush for hummingbirds and bees and, in my area, lupine, for a local butterfly whose historic habitat in pine barrens type ecosystem is threatened by man.

I adore hydrangeas. This flower is the perfect blend of color (soothing, yet vibrant and NOT too pastel) and it has fantastic shape and structure. This is also a great flower to use for a wedding. It looks lovely in a vase all by itself.
