Plant shelter

This year I need to plant round my pond, as it's in full summer sun I want to plant some nice big bushy stuff to get some shade over it and for the wildlife, obviously nothing that will drop millions of leaves in the water though - any ideas appreciated and thoroughly mulled over!

 

What about growing some of the grasses that trail over such as Stipa arundinacia or Dierama. Of course this depends on your soil around the pond. I guess with it being in full sun it would be dry to medium soil. Please correct me if I am wrong. If I can think of any others I will post them again.
