Michelle Hi Louise,
Both colors are custom made. The dark navy blue, a Sherwin-Williams Duration is a gloss exterior acrylic paint. The light blue, an exterior Sherwin-Williams Latex coating: Woodscape waterborne advanced formula, flat. Hope this will help and thank you for your nice comment

Michelle Hi "Khgott",
I think there is a misunderstanding regarding the post from Virginia, because the picture of the shed with the hydrangeas are on my property, and I don't cut them down to about 5 inches from the floor. They would not be as big as they are if I was cutting them that low.
As for your lace caps hydrangeas. I have many of them in my garden, and I learned,by experience, that they don't like at all to be cut back harshly. I usually remove the heads in March, and they bloom every year profusely, as shown in my ideabooks: "A colourful garden all year round" or " A blue garden"
Hope this will help.

khgott Yes, that does clarify things up for me! Lol! I was dumbfounded how if they were cut back that much that they'd be as big as they are! Thanks so much...your gardens are absolutely stunning!

Michelle In France, and maybe in Europe, they are called "hortensias"

Love Landscapes and Design I'm not sure if they are exactly this species but 'Nikko Blue' is very similar.
