The stones are there basically to act as a thermal mass. I'm hoping that over time a lot of soil, mulch and other
organic matter will wash down in, and I'll be able to stuff some small herbs and what not in there. Much of the spacing is just what decided to grow, I broadcast a bunch of random seed on the mounds as I built them. Some of the bare spots are where transplants didn't take, and Alex is right on the perennial stuff, I'm leaving space for it to fill in over time, and planting some annuals/cover crops in the mean time. Thanks for the comments though guys I appreciate the feedback.
