Rosa rugosa and its hybrids.
...It would seem as though many of these Rugosa hybrids might be useful in producing new varieties of hardy roses. [...] For the convenience of those amateurs who are doing breeding work with roses, the pollen of the hybrids in the Arboretum's collection has been examined in the Cytological Laboratory.  In the following discussion the percentage of fertile pollen, as determined by microscopical examination, is reported for each hybrid where buds were available for study.
New Century (R. rugosa X R. multiflora "Clotilde Soupert").
Pollen fertility 10%.
Flowers large, fragrant, flesh-pink and fully double.  Foliage light green.  This variety and Sir Thomas Lipton were both originated by the late Dr. Van Fleet of the U. S. Department of Agriculture, who is known particularly for his hybrid climbing roses, Silver Moon and American Pillar.

Rugosa Hybrids
Since the rugosa rose from Kamchatka and Northern Japan is the only absulutely hardy, ever-blooming rose that we have, it has been used considerably in recent years as a parent in the breeding of many new hybrids. These rugosa hybrids usually possess the foliage character of rugosa and partake of their hardiness, healthiness and general thriftiness of this parent but are not always so continuous in their blooming habit. Though these hybrids do not compare as cut flowers with the hybrid teas, they are far superior for general landscape planting about the home grounds. In Michigan, they are of special value by reason of their hardiness...
New Century, Hardy
An erect, strong growing variety, producing large fragrant, fully double, pale pink flowers, that are shaded deeper toward the center. This is considered one of the best of Dr. Van Fleet's originations and one of the finest of the rugosas.
