Rosa woodsii is a species of wild rose known by the common names Woods' rose,^[1] interior rose,^[2] common wild rose, mountain rose, pear-hip rose, and prairie rose.^[3]

Description

Rosa woodsii is a perennial^[4] bushy shrub which grows up to 3 metres (10 feet) tall. The shrubs can form large, dense thickets. The plant reproduces sexually by seed and vegetatively by sprouting from the root crown, layering, and by producing root suckers.^[1]

The stems are straight, red to grey-brown and studded with prickles.^[3] The deciduous leaves are each made up of several widely spaced sharp-toothed leaflets up to 5 centimetres (2 inches) long.

The inflorescence is a cyme of up to a few fragrant flowers with five petals in any shade of pink and measuring up to 2.5 cm in length. Flowers bloom between May and July and have many stamens and pistils.^[3] The fruit is a red rose hip which may be over 1 cm long and matures in August to September.^[3] They can be eaten, used in tea or as medicine.^[5]
