Propagation

Description: Propagated by stem cuttings or division of rootstock. Softwood cuttings should be taken with a heel and treated with hormone. Rose seeds should be taken from the hips as soon as ripe and planted in the open or stratified before planting.
Seed Collection: Hips can be collected as soon as they are ripe. Achenes can then be extracted by macerating the hips in water and recovering the seeds by flotation.
Seed Treatment: Cold-moist stratification is required to break the dormancy of most rose species.
Commercially Avail: yes
