Hydrangeas Can Change Color

This morning, I was perplexed because a beautiful blue Hydrangea that I had received as a gift a couple years ago, was now producing pink blossoms.  I thought I was imagining it, until I googled it, and found this post published several years ago by William Johnson

Hydrangeas Can Change Color

Hydrangeas Can Change Color

When I selected my own Hydrangeas, I wanted the Blue Purple variety. While I was reading up on them to learn how to care for them, I discovered that you can actually control the color. Allow me to add, this is true only sometimes, because where they are planted can have a strong affect on the color as well. You can better control the color when you raise the Hydrangeas in a large garden pot. 

Using Aluminum Sulfate in the soil of a potted Hydrangea will tend to make the flowers more blue or purple. Using a fertilizer high in phosphate will tend to make the flowers more pink. 

Take those same plants and plant them in the ground near a sidewalk and you will notice that even if you start out with blue colored plants, they will soon turn pick. The lime from the concrete leaches into the surrounding soil and it has a higher Ph and that changes the blue flowers to pink. 

Garden centers sell fertilizer for both generating the blue color and for generating more pink tones. If you happen to be blessed with a white variety, don't bother trying to change the color because white stays white to a pale greenish cast forever. That is what Mother Nature intended and she doesn't take too well to being messed with. 

I recently bought a new Hydrangea for a large pot and the first thing I did was to remove the flowering heads ( deadheading) and then started to add some used coffee grounds to the soil.  That tends to lower the Ph which helps offset the high calcium content of our water. That was 4 weeks ago and the new growth is just amazing. The plant, when it finishes growing out with the new growth will be about twice the original size. Before Fall sets in, I expect to have some large beautiful Blue/Purple blooms. I will be sure to show them here when the blooms come out.

Hello Myrl - and imagine you found this information through a relatively simple search.  Could you visit the Q&A section with this "secret sauce"  so that the quality of questions there might improve?  But I digress.  Once again.

Michael Jacobs - I must confess that I seldom visit the Q&A section.  I'm usually so busy trying to read posts that are part of the 3 AR groups I founded. I need another me to take on much more.

Sharon Lee - When I was a kid we had hydrangeas growing along one side of our house.  My dad often brought home metal shavings from the shop where he worked.  We had some of the richest colors on the blossoms.  But, I didn't realize it could actually change the color.

It sure turned out to a beatiful color looking at it. Now, you can match it with the theme of the season if you are up to it(e.g. christmas, winter and the like).

Thank you very much for sharing this excellent reblog selection.

Hydrangeas change color (except for the white ones) based on the pH level of their soil. The more alkaline the soil, the pinker the flowers. To make pink hydrangeas turn blue (or to keep your blue ones from turning pink), increase the acidity of soil.

Hi Myrl:

Hydrangeas are fascinating flowers and I have seen them in a variety of colors back in New England when we grew them. What fun to see this post from William, who has not been around for some time now.

Love hydrangeas, and have several varieties planted on our grounds. White and blue are my favs..although, the reds/rose/pinks are beautiful too.  I have one that blooms green and then turns white...finally fading to a blush pink. It's a stunner. D

I let them do whatever they want to do! My last home had several gorgeous specimens. One side of the house produced blue blossoms while the back of the house brought a mixture of pink and blue. One bush was half and half! They are so beautiful. My current home doesn't have any hydrangeas, but I hope to remedy that in the fall.

How fun that you can experiment and play with the colors!  I think they are pretty nice either way.

Myrl Jeffcoat , I love hydrangeas..but I know little about flowers outside of the well-known roses, lilacs, tulips, daisies, hahaha. And you never want me to be your gardener as I would probably kill all your plants and flowers...I absolutely have no green thumb at all!!!   Myrl, one of my daughters gave me 32 of her plants to care for during her move.  I still feel awful as I just about killed them all...and -- that was even though I daily watched over those plants.

But getting back to hydrangeas, I love them!!
