"Later, I had one seedling by itself, of which I have lost the parentage records, but which was so unusual that at once it attracted my attention. It may be a backcross of Aylsham and Hansa, or a sib cross of Aylsham and Aylsham No. 2. No one will ever grow it except for breeding. The plant is weak growing, single, not floriferous, not quite completely hardy, and small flowered. However, it has a most remarkable color, deep velvet-crimson, which does not fade in the sun, exactly the color of petals of Hansa when one opens the bud prematurely by force. I have used its pollen several times, and got numerous seeds, but the resultant plants bloomed on the nursery only since I have been absent. The Morden Experimental Station received material of this rose, named Quadroon, soon after it flowered first, and plants of it are, I believe, now growing on the Station grounds. It should undoubtedly be used further as a parent."
