BTW, the wall will be the same as the one pictured. This is the walkway we built in the very early part of summer. It will step down a few times and has a protruding radius on the corner that will probably be the home to a Magnolia. Roses will most likely border the wall with Nandina HB, Boxwoods etc etc....plan is being drawn. Wall will have lighting under the cap shining down the wall in addition to adding path lights to the existing walkway.
Note: Be smarter than me and don't grab a can of lime green marking paint because you've never used that color before..........it really doesn't show up very well on grass haha.
