Arbor in Afternoon Sun

My Lady Banks rose is looking gloriously ready to bloom. I love the pale yellow pompoms that cover the arbor when it's in full swing. I planted this rose four years ago, I think, and it is a *generous* grower, with many branches at least fifteen feet in length. Fortunately, since it's sending itself all over the path and I can't bear to prune it back, it is thornless!
