The clear silvery-pink color is also unusual for a rugosa, which commonly have more blue in the color.
It blooms continuously through the season. Like most selections of Rosa rugosa, it has a strong clove/old rose fragrance. The hips are crimson rather than the usual orange-scarlet, and so combine more harmoniously with the flower color. Like other rugosa hips, they are large and showy---tastiest when softened by frost, and excellent for making rose hip jelly or syrup (high in Vitamin C). It also develops excellent yellow-to-red fall color, at least in my climate.
Like other R. rugosa selections, it spreads indefinitely---and often aggressively---by suckering when it's grown on its own roots.
It has good resistance to black spot here. Also like other rugosas, it will quickly defoliate when sprayed with anything but water.
"Frau" is a mis-spelling---the correct Danish word is "Fru". I'm sure the Hastrups, like most Danes, would have been horrified to be mistaken for Germans by posterity:
"This rose was a chance seedling found in 1914 in a field of Rosa rugosa at the Hastrup nursery in Vanloese near Copenhagen, Denmark by the owner, Knud Julianus Hastrup. His wife was called Dagmar Henriette Vilhelmine and I think it most probable that her husband named the rose for her. It has been grown under the name 'Dagmar Hastrup' (we never bother with the Fru) ever since 1914 in all the Scandinavian countries." http://www.helpmefind.com/rose/pl.php?n=10698&tab=32
The registration and exhibition name is 'Dagmar Hastrup'.
