Multi-colored Hydrangea

Ashland, VA

This is a 3 yr old Hydrangea. I have seen Hydrangea's gradually change color and in the process having color variations on the blooms. I have never seen one with such distinctive color differences. I understand soil being alkaline, or acidic giving blooms on Hydrangea's their color. But could some one explain how this bush could have such prominent color differences. There are bright pink, blue, lavender and some blooms that are pink and blue split right down the middle of the bloom.

I have that same hydrangea ,it also give me gave me different color flowers and I also have the same Stella doro lily planted next to it.I took a flower to my flower show and I got a red ribbon and a Merit award which is first place,so just enjoy your plant

I read somewhere that Hydrangea color is not decided by the plant but by the PH in the soil, higher and lower produces blue, or pink, neutral would be white. Yours are beautiful.

You probably have neutral pH soil. I'd love to have that in my garden. Mine are blue since I'm at the beach. With our sand, the soil is acidic.
The only hydrangeas that aren't affected by the pH are the white ones, they're white no matter what.

My Endless Summer did the exact same thing this year......maybe my dumping cold coffee on it on occasion did it......hmmmm.

Wow...that is so cool!! I'm with everyone else on this one. I don't really know why the blooms can't make of their minds, but I would say enjoy it.

I wonder if your soil is basically neutral with bits of both acid and alkaline in different spots?

Mine also. I am pretty sure it was the rain...rain...rain....washed the acidity right out of the soil!

Sorry but neutral pH does not turn the Hydragea white, white flowered Hydrangeas remain white regardless of pH although the old, dying flowers may turn pinkish or reddish with age and decay, it's not due to the same thing as the blue/pink Hydrangea.

The colour of the pink/blue Hydrangea is governed by chemicals in the plant through inheritance and aluminium levels in the soil. Aluminium is commonly present in many soils however it is more easily taken up by plants in acidic soils hence the bluer colours in lower pH soils.

The aluminium is absorbed through the roots and taken up to the flowers where it reacts with a pigment and a co-pigment. If the aluminium is not readily taken up because the soil is more alkaline the pigment and co-pigment are still existent in the plant, they just haven't been activated.

Some Hydrangea cultivars have tendancies towards blue or pink but even these carry the ability to be changed through their chemical makeup.

For plants like yours where there are both colours present it's quite hard to say what's happening for certain. Have you bought in soil from elsewhere? Are the footings of the building alkaline while the soil tends more towards acidity? Do you water with hard or soft water? The roots appear to be finding aluminium, acid and alkaline influences in the soil.

My true blue acidic-soil grown hydrangeas that have bloomed reliably AND consistently blue for 10 years is doing this (this) year. Nothing new done to the soil or surrounding area. The only change is floods, torrential, "Noah get yer ark" level rainfall. Could that have caused leeching of cement foundation into soil ..... Perhaps......I would assume cement is alkaline.

wow it looks so amizing...what a nice post keep sharing these kind of useful information.

I think the greenish yellow flowers are the youngest and as they age they become purplish blue and at the last stage they take on the pinkish hue. This phenomenon is common to few other plants and flowers

Dahlia you may be able to enlarge and see that those well formed blooms have some pale green, blue and pink on same bloom. My experience with our shrub is that the individual blooms go blue totally and when they fade..they fade uniformly. The blooms don't have different levels of maturity on each separate bloom but yes some blooms are older than others and age accordingly.

This is my plant that was in the yard when I bought the house 7 years ago

I must share my results from my garden club flower show with my garden buddies . That hydrangea that's In the picture won first place and a merit award at the flower show , I was so surprised

Well, it is gorgeous. Looks perfect.

Have any of you guys ever tried shoving copper tubing in the ground around your hydranias? It is supposed to turn them purple. My personal favorite is still the blue. I put in a picture of one of ours before a freak cold snap nearly killed it.

Wow - a beauty. I have heard of copper nails being used in the garden. We have naturally acidic soil so never had to explore the method. -- But I think if purple were possible-- I'd have seen it here. Of course right here on Dave's I have seen folks post "true blue" flower photos that were purple to me -- so no accounting for individual opinions about what is purple and what is not and also there are differences in monitor displaying colors.

My wife received a beautiful pink hydranis while she was in the hospital. I planted it out away from the house hoping it will stay pink. I'm looking for it turn blue like the rest. If it does I will play with it some and see If I can get it to turn back.
