EXTERIOR WALLS SHOULD BE 3-D IN AREAS. A wall fountain, a birdhouse, exquisite shutters, espaliered plants, a vine, art. Whatever ties in with your interior design. Low maintenance, above, means don't plant the pots.
* In the 1/2 face use an artful arrangement of pine cones + Spanish moss.
* Put a bonnet on the woman with an arrangement of dried hydrangeas + spike of dried
butterfly bush blossom.
* Give the bearded man a circa 1960's NASA crew cut of clipped twigs from a nearby tree.
You get the idea. I'm curious what you've come up with.
Garden & Be Well, XO Tara
