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.
Arnoldiana (R. rugosa X R. borboniana "General Jacqueminot").
Pollen nearly all sterile.
This was another of the hybrids produced by Jackson Dawson. The flowers are single and of a brilliant shade of crimson. The bush is a very vigorous grower.

Arnold. (Dawson, 1893.) Medium-sized single blooms of glowing scarlet-red. The plant is very strong, with foliage less wrinkled than the type.
A profusely flowering, very valuable shrub. Scant or no bloom late in the season but very handsome in May and June.

Rose breeders are singularly reticent about the plants they have used in their work, and there appear to be no printed records of the parentage of any of the Rugosa hybrids with the exception of the two which have been created in this Arboretum.
...The two Rugosa hybrids raised by Dawson at the Arboretum have proved to be good garden plants. [...] The Arnold Rose, R. Arnoldiana, was made by Dawson, by crossing R. rugosa with the hybrid Tea Rose, General Jacqueminot. It is a stout bush with good foliage and large, bright red, single flowers, and when in bloom perhaps the showiest of the Roses in the Shrub Collection.
