Rosa pendulina

Rosa pendulina, also known as the alpine rose or mountain rose and formerly widely called Rosa alpina, is a wild rose of the mountains of central and southern Europe. It is a climbing or rambling shrub between half a metre and two metres tall, with deep pink to fuchsia flowers that brighten toward the centre and relatively few thorns, especially on the upper stems. The oblong fruits hang downward, which gave the species its name, since pendulina refers to the pendulous hips. It grows in the subalpine zone of the Pyrenees, Massif Central, Alps, Carpathians, Apennines and Balkan mountains, beside streams, in forest openings and on rock piles at roughly 350 to 2,500 metres. Gardeners have grown it since about 1683, and it has contributed to many rose cultivars and hybrids. It is hardy to USDA zone 4a and has escaped from gardens in New England.
