Ube Komachi
This Mini climber, profusely flowering with light pink bloom, seemingly bred in Japan in 1991 by Harada, is also planted in Eltville (see. 'Schönes Eltville') in a little park. I suppose that it was one of the guest presents brought by Japanese rose friends on one of the visits to Eltville which is a partner town of Hiroshima.
