On a visit to the Edinburgh Botanic Gardens, we were most impressed with a hybrid form of our much-loved R. carolina, the other parent being R. rugosa. A large circular bed had been planted with this tall rose, which had perfect foliage, handsome sprays of large rosy-red, single flowers, and slender elegant buds. The label read simply Carolina x Rugosa; so we hope in the future to hear more of it, as it will certainly become popular when well known.

65 - Rosa humilis x rugosa Koehne...
R. humilis x rugosa Koehne, Deutsche Dendrol. p. 294 (1893).- Keller in Acherson & Greabner, Syn. Mitteleur. Fl. vol. vi. p. 308 (1902)

Stem low, spreading; prickles small, moderately stout, sometimes in intrastipular pairs, without any intermedia aciculi. Leaflets 7, oblong, obtuse, simply serrated, the larger an Inch or more long, glabrous on the upper surface, pubescent beneath; petioles pubescent, not glandular; stipules adnate, with deltoid entire free tips. Flowers solitary; pedicels long, glabrous, slightly aciculate. Calyx-tube ovoid, slightly aciculate; lobes lanceolate with a long point, simple, 1 in. inch long, pubescent and furnished with many aciculi on the back. Petals middle-sized, dull purplish red. Styles free, not protruded beyond the disk.

This hybrid between Rosa humilis Marsh. and Rosa rugosa Thunb. was raised not long ago in America. The characters of the humilis parent greatly predominates in it over those of the rugosa parent. Although the colour is not particularly pleasing, it is nevertheless a useful Rose, and is especially well adapted for the wild garden and for hedges and plantations. It is exceedingly floriferous, hardy and quick growing, and forms a thick, compact bush, while its abundant and bright-coloured fruits make it very ornamental in the autumn.
