Placement for hydrangea

[Laurasanford111]

I have a mop head hydrangea pink one on the opposite side of the garden that thrives. I love how easy they are to look after, I haven't killed it (yet) I would love a Hydrangea Annabelle, although I'm torn between limelight and Annabelle, someone is selling 4 year established ones near me cut back ready to plant.
Anyway my question is this, what side of the garden should I plant it, on the left next to fence or by the wall? The idea is to have this section more closed in if that makes sense I have a climber over that arch doing well and one on the fence so I thought having the hydrangea by the wall would block off some view of the shed etc, anyway let me know your thoughts! Oh and if you have either one of these hydrangea which one you would recommend more! Thank you

We have a limelight hedge- it looks great, just cut it back once a year in the spring. The heads aren't as heavy as Annabelle, so don't droop, however Annabelle can look stunning.

The spot by the wall looks good but I'm sure either would work.

If you want Annabelle, search out Strong Annabelle, because otherwise, even with a support in place, the flower stems are likely to droop and snap.
