Hydrangea blooms are green

Can I get a hydrangea that has green blooms, Blue? Thanks. I don't know for sure, but am guessing this plant is at least 8 years old, as our house is, and that makes sense, we bought it this April. Thanks.

    The answer is maybe. Depends on the variety and how receptive it is to the PH change from adding more aluminum sulfate. If it is a newer variety such as 'Pistache' you probably won't be able to do much with it. But it certainly won't hurt to try. Sometimes if the Hydrangea is getting very little light it won't fully develop the bloom. Do you remember if the blooms fully opened? You don't happen to have a picture of the bloom or the plant do you?
  • There are so many hydrangeas with each doing their own show of color. You bought the house in April but the hydrangea was already there? Or you just bought the hydrangea? Either case sometimes the flower will be green then turn either blue or pink depending upon the type of hydrangea and/or the soil. Also every so often (and I just had this happen this year) a hydrangea will be green all summer and never turn colors. You need to know the type of hydrangea because some hydrangeas are white, green, blue or pink and no matter what you do they will be that color. Many hydrangeas that are pink or blue can be "turned" by acidic or alkaline soil with manipulating using lime, aluminum, some say coffee grinds, etc. Here is a link with some helpful hints http://www.hydrangeashydrangeas.com/colorchange.html

    Thank you for the suggestions but this doesn't answer my question because

    Here are pictures of the hydrangea, yes, it was already here in the yard when we moved in, but the house was built in 2005, so I am assuming the plant was put in that year, too.
    • @Carolyn Hoxton The size of the blooms reminds me of Annabelle Hydrangeas (hydrangea arborescens) which are white when they first bloom then they turn green. Annabelles were readily available back then and were about the only hydrangeas sold. And you cannot make them any other color.

    yes, they were white at first, and thanks, I will have to do with these the color they are. I actually have another hydrangea at our other house, but it is 70 miles away, and I didn't have time to dig it up when we moved...now it is rented for 3 years, so hopefully, then I can go get it, it is blue.

    Nikio Blue will turn all kinds of colors. Just leave them alone and you can get blue, pink, green and even red in the fall. Blushing bride blooms white red and green in the fall.

    you can change the colors Test the water's pH levels that you typically use to water your plants. It needs to be around 5.6. Lower the pH levels in the plant. This is done by increasing the aluminum in the soil. Mix 1 tbsp of aluminum sulphate and 1 gallon of water. Water the plant with this mixture 2 to 3 times during the summer months. Check the soil's acidity. To change pink to blue, you need a 5.2-5.5 pH reading. Fertilize the plant with one that is low in phosphorus and high in potassium. Add coffee grounds, fruit and vegetable peelings and grass clippings to the plants soil to help change the pH levels as needed. Blue to Pink Check the plant's pH. It needs to be between 6 and 6.2 to change its color from blue to pink. Raise the pH levels by adding limestone to the soil. Fertilize the hydrangea with fertilizer high in phosphorus. Add wood ashes to the soil if you still need to adjust the levels.
