Form

R. moschata is a shrub (to 3m) with single white 5 cm flowers in a loose cyme or corymb, blooming on new growth from late spring until late autumn in warm climates, or from late summer onwards in cool-summer climates. The sepals are 2 cm long with slender points. The flowers have a characteristic "musky" scent, emanating from the stamens, which is also found in some of its descendants.

The prickles on the stems are straight or slightly curved and have a broad base. The light- or greyish-green leaves have 5 to 7 ovate leaflets with small teeth; the veins are sometimes pubescent and the rachis

s are narrow with spreading, free tips. Small, ovate fruits called hips are borne, turning orange-red in autumn.

This species has historically been confused with Rosa brunonii, a closely related, tall-climbing species from the Himalayas that bears flowers in late spring and which possesses a similar, musky scent. They can be distinguished in gardens by their season of flowering and by their differing growth habits.

The variety 'Plena' bears semi-double flowers, and a form with study name "Temple Musk", found in the United States, bears more fully double flowers.

Cultivation

It has been contended that no truly wild examples of the musk rose have been found, though it is recorded in cultivation as least as far back as the 16th century. It is important in cultivation as a parent to several groups of cultivated roses, notably the damask rose and the noisette group, and is valued for its scent and for its unusually long season of bloom among rose species.
