Grow low groundcovers between flagstones to give your patio an old-world, established feeling. Or try the same with brick; just pop a few random bricks out of the ground and place low perennials (such as this golden creeping Jenny) in their place

The walls that define this space are gorgeous and bring the inside out. I love all of the greenery and shade as well.
