Miscellaneous Note - Frank L. Skinner approx 1935 - [no photos]

Rose Dorothy Fowler (Rosa rugosa-acicularis x spinosissima, double white). A bush up to 3 ft. with foliage that shows the influence of all three species involved; flowers 3 - 3 1/2 inches across, very fragrant, soft clear pink in color, flowering during June. The coloring in the photograph is not very good. In this photograph are also shown two blooms of R. blanda x blanda-Clothilde Soupert. These are rather dainty little flowers, quite fragrant but rather thin in the petal. (Where two Rose names are used in the pedigree as Blanda-Clothilde Soupert it means that one parent was a hybrid between the two varieties named.)
