Breeder's notes:
Graceful, mounded growth habit, much better than that of either of its parents. I can only praise this rose. Even the lack of hips is a pro because thus the bush looks tidy all year round.
Notes:
The pollen parent is almost certainly Rosa pimpinellifolia 'plena', known as 'Juhannusruusu' in Finland. Very few hips, suggesting that it is triploid. Does not produce pollen. No suckering and no sign of disease so far (2013).
