Since the last post, I've changed the shape slightly and took away a little bit of square footage. My goal was to have a native rain garden and I mostly took height and bloom time into consideration (besides being a native species. The square footage now better corresponds to my calculated roof area. The two circles on the house are my gutters. I just realized I totally forgot to add the pipe into the mix. It would be coming from the rain gutter on the right. The one on the left has a smaller roof section and was not calculated into the garden. I would love any feedback on the plant choices! Thank you!
