Paeonia sinensis fl. pl. 'Gretchen' (G. & K.)
This variety incarnates the perfect beauty of the noblest peony, and we are sure that it will find appreciation everywhere. The palnt itself grows short and stocky and does not need a support. The blooms on taut and firm stalks are ivory white and have a light flesh-coloured shading. This sort is especially suitable for planting in groups in a landscapewise preferable location due to its floriferousness and its excellent habit. 1 piece M 5.-, 10 pieces M 45.-
