HI -- It would help to know what garden zone you are in . But you could go to your local garden center and they will help you with the proper choice for that area . They will need to know which way it faces - north side or south full sun and so on. I can see why Hostas are not right for there because they are better in the shade . Look at daylilies for that area - Stella D Oro - I think that is the name -- they would look very nice there . They are pretty tough and might work for you .

Are you saying the concrete patio is a complete circle around your house like a track? What purpose does that serve, if any? Maybe it is time to reconsider that too.

Best.
