The Royal Botanic Show, July 4th, 1913.
William Cooper (Hugh Dickson, Ltd.), Silver-Gilt Medal. — A fine large-petalled Hybrid Tea, with not too many petals perhaps, but seemingly holding them well together, as some of these few-petalled Roses will, of a very brilliant cherry red, flowers of good shape, pointed and very fragrant. It was awarded the Silver-Gilt Medal at the same Show last year, and the award should not have been duplicated. No doubt it was staged for the Gold Medal.

p.153) Royal Botanic Gardens, Regent's Park, July 9th, 1912.
William Cooper (Hugh Dickson, Ltd.), Silver-gilt Medal. -- This Rose must not be confused with Mrs. William Cooper from the same raisers. It is a fine upstanding flower of good pointed shape, deep rose in colour, a good grower and vigorous. It was very well shown by the raisers, and had it been a little more distinct in colour would doubtless have secured a higher award. As seen growing at Belmont it is undoubtedly a fine Rose -- a Hybrid Tea.
