'Frühlingsmorgen' Kordes, Germany, 1941. A hybrid of 'E. G. Hill' x 'Cathrine Kordes' crossed with Rosa pimpinellifolia 'Grandiflora'. I hesitate to claim that this is the most beautiful of all roses with single (five-petalled) flowers: there are so many claimants. But appraising a flowering spray can easily suggest that here is a rare example of the breeder's art which equals if it does not eclipse nature's best efforts. Apart from the beauty of the clear rose-pink large petals which pass to clear, pale yellow in the centre, the flowers have the incomparable attraction of maroon coloured filaments and anthers. It usually gives a crop of flowers in late summer as the generous mass in the spring. The bush is on the sparse side, leaves leaden green. 6 feet by 5 feet. A few large, maroon-red heps are produced.
