Rosa x warleyensis was also raised from seeds that had been sent to Kew years earlier. In her comments she described it as a hybrid between R. rugosa and R. blanda, having characteristics of both. The note that it was “very free flowering” leads one to believe it had R. rugosa’s remontancy. Some botanists reversed the parentage suggesting R. blanda was the seed parent. [Ed. note; Baker gives two German botanical sources that suggest an earlier synonym may be R. rugosa x R. virginiana. The 1893 Koehne source has no botanical description and Koehne actually states that he had not seen the rose. The 1902 Ascherson source merely quotes Koehne.]

Rosa warleyensis (nov hyb.) Rosa rugosa x blanda.
Rosa warleyensis was raised from seeds which were sent to Warley many years since and which were said to have been gathered from a wild Rose. It shows unmistakable signs of Rosa blanda Ait. influence, and is in fact about midway between its two parents. It is a pretty and free-flowering Rose quite distinct from the generality of Rosa rugosa hybrids, and it well deserves a place in the garden.

59 - Rosa Warleyensis (nov. hyb.)...
R. rugosa x virginiana Koehne, Deutsche Dendrol. p. 298 (1893).- Keller in Ascherson & Graebner, Syn. Mitteleur. Fl. vol. vi. p. 307 (1902).
Stem much armed; prickles slender, subulate, passing gradually into copious aciculi, some in anfrastipular pairs. Leaflets 5-7, oblong, middle-sized (1-1 1/2 in. Long), green, less rugose than in Rosa rugosa, glabrous on the upper surface, thinly pubescent, not at all glandular beneath; petioles pubescent and aciculate; stipules adnate, broad, not gland-margined, with ovate free tips. Flowers solitary; peduncles naked. Calyx-tube globose, naked; lobesovate at the base, with a long point, 1/3-1/2 in. long. Petals middle-sized, pink. Styles free, villous. Fruit globose, naked, bright red, 1/3-1/2 in. in diameter, crowned with the erect persistent sepals.

The drawing represents one of the many Rosa rugosa Thunb. hybrids. In all Rose hybrids and crosses there is generally one character which persists until at least the third or fourth generation. Thus the Rosa multiflora Thunb. crosses have ciliated stipules, and in the Rosa rugosa hybrids the character of the reticulated, deeply veined, rough, dark green leaves is found with but little modification in all the hybrids now known. Rosa warleyensis was raised from seeds which were sent to Warley many years since and which were said to have been gathered from a wild Rose. It Shows unmistakable signs of Rosa blanda Ait. influence, and is in fact about midway between its two parents. It is a pretty and free-flowering Rose, quite distinct from the generality of Rosa rugosa hybrids, and it well deserves a place in the garden.
