Bamboos & grasses to help hide my shed, any recommendations?

Evening all,

I am trying to hide my shed and as part of my plan I was thinking of planting some tall bamboos/grasses in containers (so I can easily control them/they wont get out of hand) and I was wondering if anyone could recommend any particular plant groups/species?

Also should I raise the plant pots with some bricks so the plant roots wont grow into the ground soil and spread/become uncontrollable?

Thank you for your replies,

Samuel
