IMPOSTER ROSE

The idea is, at the front of my home, to have a long bed of glorious yellow Arthur Bell roses. Unfortunately, I miscounted how many I would need when I first planted them and needed to buy another. I bought another, except it had the wrong label on it and now it has flowered I see it is no Arthur Bell at all but an imposter. What is so odd is that the buds look exactly the same as those of Arthur Bell - yellow with a tinge of orange. What is rather wonderful is that, although the rose is the odd one out, it is an absolute beauty! I might need to move it and put in an Arthur Bell in time but I won't be giving it away or throwing it away. I wonder what its name really is.
