I hope I might receive some suggestions and I think this is where I should ask.

I should do a little explaining.

I have a grand vegetable garden. To water my garden I built a sprinkler that spins a circle above and delivers water in a beautiful fashion to all my plants.

Now when I erected this sprinkler/water feature I had to secure it with 2x4s and such and in the very center under the head or circle I have made a window box like thing.

Now, the question is. What would you suggest I plant in this container. It is 2 feet long and 5-6 inches deep. It sits right under the sprinkler so it gets the most water, and the plant would be watered from over head, gently.

I don't know if this would be classifed as a bog situation as I did put drainage holes in my bottom, it's just going to get watered everyday.

I love the idea of something cascading down and flowering, or perhaps some type of herb since it is in the veggie garden.

Thank you and I look forward to you're comments.
