Thanks a lot for your kind comments.
I absolutely love Limelight, outstanding shrub, very decorative.
I don't remember the name of 'pale blue' Hydrangea, but I bought it as white and after I applied soil acidifier (to keep my pink hydrangeas blue), the flowers turned very attractive baby blue color. I like this effect a lot.

What did you use to acidify your soil? I have an old concrete pond with a "patina" of different pale blues and I have hydrangeas around it. I want all the plants there to be blue or white. Some are blue but some have gone pink. I wonder if there is something I can put around the plants to blue them up, or does it have to be dug in?

No, no, no. Do not dig out your pink bushes. You can easily turn them blue.
First of all, I fertilize my hydrangeas with Espoma 'Holly Tone' - fertilizer for acid loving plants, then I apply soil acidifier. There are several products on the market - Aluminum Sulfate, Ammonium Sulfate...
I buy this stuff from Lowes or Home Depot.
How close are your hydrangeas to the concrete pond? Concrete might contribute to the pink color of your plants. Concrete leaches lime that promotes pink color.
I think you can still turn your hydrangeas blue by multiple applications of acidifiers.

They are growing along an old concrete path that borders the pond. I am fortunate to live near Vintage Gardens, and I had Gregg Lowery come a few yrs ago and give me a consultation on my back garden, since he specializes in all things old in the rose world. I remember him pleading with me not to take out the pond or the paths, stairs, etc. because "They don't make concrete like this anymore!" Our hardscape was probably done in the twenties. The hydrangeas mostly came from Vintage too, and they are old European varieties, except the one that stayed blue, which I found at Whole Foods! Thanks for the advise!!
