The Moss Rose (Rosa centifolia muscosa) is supposed to have originated from an accidental sport of the common Provence, and this supposition is strengthened by the fact that the seed from Moss Roses often produces plants having flowers entirely free from moss.  The earliest account we have of the Moss Rose is that it was imported from Holland to England in 1596.  The following varieties may be ranked among the best in this class:
Baron de Wassenaer — A vigorous grower, with well formed bright red flowers produced in clusters.
