More information

Echo was a repeat-flowering polyantha rose. It was one of the few repeat-flowering sports arising from a single variety. The line did not end with Echo: several others originated from this rose, including Anneke Koster, and from Anneke Koster came Dick Koster. Dick Koster in turn produced many sports—its offspring include Margo Koster and Morsdag, and from Morsdag came Orange Morsdag and Vattertag. These roses differ only in colour: Dick Koster is dark pink; Margo Koster is bright orange with a silvery pink reverse of the petals; Morsdag is dark red; Orange Morsdag is bright orange; Vattertag is also orange. The petals curl inward to such an extent that the globular blooms do not open until they fade. In wet weather the blooms can rot and the petals become moisture-stained. All varieties bloom abundantly and are easy to cut.

Sport Appeche Koster. Flowers are dark pink, buttercup-shaped, small (3–4 cm), double, in inflorescences of up to 30. Leaves are light green and pointed. Shrubs are dwarf, low-growing. Winter hardiness is weak.
