looks like "cor-ten" again. Raised bed vegetable beds like this aesthetic to you? I like the idea of using wood planks and sticking to that theme, but cor-ten is good for separating spaces into clean lines (rock from turf from ornamental grasses).
A brick wall and structured lawn create a foundation for this gorgeous cottage-style planting bed. This would look absolutely FAB in the Pulte Millbrook house plan's yard. Must have French lavender in the flower beds!
