Greenland. Pehrson/Seidl. 1998. Herbaceous hybrid. Parentage: Sanctus x a non white F3 derived from Silver Dawn. White double form, with large inner petals, ruffled, cupped and crimped; outer petals large, broad, shaded green underneath. Stamens clustered around small carpels tipped red. Tetraploid. Fertile pollen when used on other tetraploids, produces seed with some effort.? Medium large foliage, husky upright stems, usually no laterals. 30-36? height, midseason bloom. Slow to mature, but worth waiting to see a mature plant in the garden. Photos courtesy of Leena Liljestrand.
