This rose was bred (or discovered) by an amateur in the vicinity of Thionville, Moselle, and sent to Pirolle (see authors), who distributed it to Vibert, Laffay, Sisley, Godefroy and other nurseries.
A study in 2006 showed that 'Quatre Saisons Blanc Mousseux' is genetically identical to 'Kazanlik' and 'York and Lancaster'.

Royall River Roses says this rose has long, elegant buds that open to semi-double, sweetly fragrant white blossoms. The buds and stems are covered in dense brownish green mossing...

In RoseGathering's photo, there's a bloom of 'Perpetual White Moss' Shown with 'Autumn Damask' sported on the same plant. What a great illustration of the two roses!
