Site of new butterfly garden

Here is the site of my next project...a butterfly garden. I'm just finishing the wall by filling in with topsoil. I'm not going to start planting until the end of July. Have to finish a few other things before then.

The plan all along was to fill in this area with flowers. Making those flowers butterfly friendly just gives me some extra focus as to what plants I want. The picture doesn't give any idea as to the size of the area. The wall is 6 feet from the garage. the total length of this bed is about 100 feet, but the butterfly garden will be only 50-70 feet, depending on how ambitious I get. More to follow.
