"Pest-Proof, Fool-Proof, All-Purpose Roses". Some Outstanding Species Described By C. R. McGinnes
I will list briefly the characteristics of some of the outstanding sorts among the more than two hundred which we have in our garden at this time.
The best known everblooming species are R. chinensis mutabilis and R. rugosa and their hybrids. [...] R. mutabilis is absolutely everblooming and bears flowers at the same time all the way from a pale straw color to a dark crimson. It could be used for any purpose that Polyanthas are. It has also been catalogued under the name of Chamois by Kordes and by one American nurseryman.
