Oh, so much fun working in my “yarden”!! I checked my tarp shelter for “spiky” things and selected two items that had previously been plant stands. Turning them upside-down, I had eight more slender metal receptacles for bottles or vases. So I placed them at the foot of the bottle bush and call them “bottle weeds.” Earlier I exchanged the white plastic pipe “spacer” for “quarter-round” wood spacer. Far more attractive (imho).
