The hydrangea macrofilia don't like to be in too much sun and will wilt, especially not good if in afternoon sun. The macrofilia are the blue ones (and sometimes pink) that bloom on old wood.
The limelights and the paniculatas (also called peegees) are fine in full sun. They are the white ones.

lol .. be kind people

(just me :-)

We have the macrofilia which bloom pink for us. I didn't realize the white ones were more drought resistant (or sun resistant). Thanks for the info.

you're welcome!
