that's Dorothy Perkins, a large once blooming rambler that roots easily from cuttings and mildews easily as well.

It's pretty when it blooms, isn't it? It's a shame it mildews so much. You'll often see a cherry red-pink rose blooming on roadsides, too, called Excelsa or Red Dorothy Perkins.

Thank you! The rose is indeed impressive. Do you think it just escaped from somebody's gardens?

Dorothy Perkins has escaped from gardens around here. I often see it growing in front of abandoned homes or where there used to be houses. But it's so vigorous it often ends up a long way from where it started!
