Frühlingsmorgen - Hyb. spinosissima (R. spinosissima altaica x (Cathrine Kordes X E.G. Hill)) Described by G. S. Thomas as follows: 'the most exquisite of single Roses. Each bloom is a model of beauty, pink in the bud, opening to rich cherry-pink at the edges, soft yellow at the centre where there is a ring of maroon stamens. Late May and June and occasional blooms later. More compact than Frühlingsgold'. Germany: Kordes, 1942.
