Other forms: trellises, trelles
A trellis is a light frame of crossed strips for climbing plants. Fix a trellis, train the rose up the trellis, a trellis panel.
It must stand a little off the wall so that air moves behind it and the plant has something to grip, and hinging it at the bottom lets you lower the whole thing to paint. Climbing roses need tying in; clematis and vines hold on themselves.
