They are extremely cold hardy and disease resistant, hence they are used to create new varieties for subarctic climates like northern Scandinavia and Canada.

These magnificent shrubs can withstand shade and semishade, and are easily found abandoned in semi wild situations.

In Sweden and Finland the French bred 'Minette' has been considered a wild rose called R. × suonum (Mustialanruusu).

[3] Found alba roses are very common in Germany; some may be local variations, but some could be old cultivars waiting to be renamed.

Rosa × alba is hexaploid,[1] with six sets of chromosomes in each cell, which means that it interbreeds only rarely with the more common diploid, tetraploid, and pentaploid roses.
