trellis laid on an angle for climbing plants; good solution for heavier climbers (quash, watermelon) b/c of thickness & strength of wood panel. Once the vines start climbing the trellis, they provide shade for lettuces underneath.
The two seats in the Scampston Walled Garden make the focal point without which this picture would be less interesting. I would have used two Adirondack seats painted a colour to complement the scene. This is the Perennial meadow in summer.
