About Rosa glauca Pourr.
Rosa glauca Pourr. is a deciduous shrub. It grows 1.5–3 m (4.9–9.8 ft) tall, with arching, cinnamon-coloured canes that bear sparse bristles and thorns. Its leaves are distinctive: they are glaucous blue-green, sometimes shifting to coppery or purplish tones, covered in a waxy bloom, measure 5–10 cm long, and have 5–9 leaflets each. It produces fragile, clear pink flowers 2.5–4 cm in diameter, borne in clusters of two to five. Its fruit is a dark red, globose rose hip 10–15 mm in diameter. This rose was not widely cultivated in gardens until the end of the 19th century. Its flower petals detach easily when hit by spray from watering hoses, and also come off easily due to wind and rain. Outside of its original native range, the species has become naturalised in northern Europe further north, particularly in Scandinavia. It has been awarded the Royal Horticultural Society's Award of Garden Merit. A hybrid between this species and Rosa rugosa has been given the cultivar name 'Carmenetta'.
