Future Roses for the Prairie States
J. L. Budd
Of the newer hybrids of R. rugosa now quite widely tested, the most desirable are I.A.C. (Fig. 2183), Ames, Madame Georges Bruant (Fig. 2184), Madame Charles Frederick Worth, and Thusnelda. Kaiserin (Fig. 2185) is also to be commended. It is suggestive that these have come from crossed seeds of what is known in Europe as Rosa rugosa, var. Regeliana (p. 1556), and which we know as the Russian Rosa rugosa. The first two named came from seeds of Rosa Regeliana introduced by the writer in 1883 crossed with pollen of General Jacqueminot, and the last three were developed from seeds of R. Regeliana in Germany as stated by L. Spath, of Rixdorf near Berlin. They are all fine double Roses of the class shown in Fig. 2183, of the two produced at Ames, and all have retained to a large extent the foliage and habit of blooming of R. rugosa. The Russian R. rugosa as introduced from Russia by the writer is divided into two very distinct classes. The one from the Amur valley in North Central Asia is a very strong, upright grower with lighter colored bark, stronger thorns, thicker and more rugose leaves, and larger flowers than the Japan type, but its hips are smaller. The one from Russia in Europe is spreading and pendant in habit. When 4 ft. in height it has a spread of top of fully 6 ft. Its leaves also have a darker shade of green than the Japanese type, and its buds are longer, more pointed, and show between the narrow folded petals shades of rich red and crimson. Its clusters of flowers also differ, as it has four to five flower-buds together, while the Japanese type has only two to three. In addition, we now know by trial that both these Russian types may be grown successfully two degrees farther north than the Japanese R. rugosa.
