Two forms may be recognized: f. roxburghii, which has double or semi-double, reddish or pink flowers 5–6 cm in diam., and f. normalis Rehder & E. H. Wilson (in Sargent, Pl. Wilson. 2: 318. 1915), which has simple, pink flowers 4–6 cm in diam. The specific epithet was spelled “roxbourgii” in the protologue.

The edible fruit are very rich in vitamins and have a sweet, sour taste; they are used medicinally and to ferment wine. The roots are also used medicinally. The species is also cultivated for ornament, for its showy flowers, or as a hedge because of its abundant prickles.

Rosa roxburghii ( Fransızca )

wikipedia FR tarafından sağlandı

Le rosier châtaigne (Rosa roxburghii) est une espèce de rosiers, classée dans le sous-genre Platyrhodon, originaire de Chine (Anhui, Fujian, Gansu, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Shaanxi, Sichuan, Yunnan et Zhejiang) ainsi que du Japon.

On le rencontre dans les forêts de montagne, sur les rives des cours d'eau et sur les pentes entre 500 et 1 500 mètres d'altitude.

Il en existe deux formes :

Rosa roxburghii f. roxburghii, aux fleurs doubles ou semi-doubles, roses à rougeâtres, de 5 à 6 cm de diamètre,
Rosa roxburghii f. normalis Rehder & E. H. Wilson, aux fleurs simples, roses, de 4 à 6 cm de diamètre.

Ce rosier a été dédié à William Roxburgh, médecin et botaniste écossais qui fut notamment directeur du jardin botanique de Calcutta.

Il doit son nom vernaculaire de « rosier châtaigne » à son fruit couvert de piquants comme une châtaigne.

Synonymes :

Rosa hirtula (Regel) Nakai,
Rosa microphylla Roxb. ex Lindl.
