My impression is Rodhatte blooms are smaller than Eutin, petal count is lower and the petals give the sense that the bloom is often not circular in outline
Canadian Rose Annual pp. 70-75 (1979) Development of the Floribunda NIELS DINES POULSEN Rose-breeder and Grower Kvistgaard, Denmark
In my opinion, the true forerunner of the floribundas is "Little Red Riding Hood" —1911 (Rodhaette). It was raised by my late uncle "Dines" who worked a couple of years in his young days for Peter Lambert in Germany and got a lot of inspirations from this great rose hybridizer. This variety is still in commerce in Scandinavia — believe it or not.
