About plant names...

The rugosa rose is native to eastern Asia, northeastern China, Japan, Korea, and southeastern Siberia. Introduced as an ornamental plant in the 1800s, it is well established now, common along the seacoasts because it is tolerant of salt spray.

Identification: Rugosa rose is easy to identify. It is a shrub 3-6' (1-1.8 m) high, with stems that have, to use the precise scientific term, zillions of thorns. Big scary ones, tiny insignificant ones. Far more than on any rose I have ever seen. The thorns are straight or nearly so, varying from ⅛-⅜" (3-10 mm) in length.

Leaves are in odd pinnate clusters of 5-9 leaflets, usually 7. The clusters are 3-6" (8-15 cm) long, and the individual leaflets are 1-1½" (3-4 cm) long. While most rose leaves have relatively smooth surfaces, these leaves are shiny, dark green, and deeply veined (technically, rugose, hence the species name). Leaf undersides are light green from dense feltlike hairs. Flowers are white or pink, 2½-3½" (6.3-8.9 cm) around, with five petals. They may be solitary on in clusters, and appear from June to August. Fruits are glossy “rose hips” up to 1" (2.5 cm) around, ball-shaped but somewhat flattened, orange to deep red.

See our wild rose comparison guide for further information.

Edibility: Rugosa rose hips are edible raw, and used for jams and to make tea. They are high in vitamin C.
