The roses and briars (Rosa spp.) are large-flowered, prickly shrubs. Their leaves are imparipinnate. The actual fruits are achenes which, however, are not visible, but enclosed by the enlarged receptacle, the whole being called a hip.
The genus comprises between 100 and 250 species, depending on the defining criteria. They are distributed over the temperate regions of the Northern hemisphere. Roses have been cultivated in China and the eastern Mediterranean at least for 4,000–5,000 years.
Rosa glauca is native to the mountains of Central Europe. It has been a fairly common ornamental in Finland since the 19th century. This species does not produce suckers. Its stems are erect and fairly tall. The slender, spreading young branches are covered in a waxy bloom. Prickles are fairly sparse, and they are slender and straight or slightly curved.
