Drooping Bombshell hydrangea

Hi all,

I planted a Bombshell Hydrangea last Saturday. It's been looking good all week only to wake up this morning to it drooping. I've attached a photo.

Any advise to why and possible ways to cure the issue would be great. I'm a novice gardener so only starting out.

Thanks

Stu

 

Maybe the rain yesterday has weighed down the blooms?

 

Yeah I think that's what it's been, they seem to have perked up a bit now.
