Possible Garden Site

So, our office has a mostly unused courtyard.  It's overgrown with jasmine, as you can see, and rarely even cleaned out.  There is a drain in the middle of it so it doesn't flood but currently it's covered in leaves so I'm not sure how effective it really is.

My wife has heard me talk about the little courtyard and decided recently that it might be nice to do a little gardening in it.

The area shown really is the best spot in it for gardening but it'd be a lot of work to get it in a state that you could grow anything there.  We're already pretty busy people with her writing events going on throughout the spring and summer but we'll see.  First I'd have to ask my boss anyway but I think there's a pretty good chance he'd not mind as long as it really was kept up.  The only real pests would be the squirrels.  So as long as I plant something they don't mess with I should be ok there.

It's about 5 feet wide there and a bit longer so I can see something growing pretty good.  I'd have to figure out how to water it though.  And keep the water from getting into the building since it's up against the windows.  Maybe a strip of daylilies there?
