Habit:  shrub

Description:  "Evergreen scandent shrub. Stems glabrous, scattered with sparse prickles; branchlets sometimes with thinly glandular hairs. Leaves mostly 3-foliolate, rarely 5; leaflets elliptic or ovate, the terminal one 5-7 cm long, 2.5-3 cm wide, the lateral ones smaller, acute or obtuse at apex, acute at base, glabrous on both surfaces, serrate; rachis glabrous and sparsely prickled; stipules adnate to the base of rachis, linear, up to 1.2 cm long, glandular-hairy and serrate along the margin. Flowers solitary, 5-7 cm long; hypanthium and pedicels densely prickled; sepals persistent, prickled outside; petals white, emarginate. Fruit pyriform, up to 3.5 cm long, 1-1.5 cm wide, densely prickled" (Li et al., 1977; p. 99).

Habitat/ecology:  Very common in thickets at low altitudes (Li et al., 1977; p. 99). In Hawai‘i, a sprawling thorny vine escaped from cultivation and naturalized in mesic forests.

Propagation:  Seed

Native range:  Mainland China, Japan, Taiwan, Vietnam (Li et al., 1977, p. 99; GRIN).

Control: 

Chemical: "Katie Cassel (Kōke‘e Museum) reported that Cherokee rose was susceptible to 20% triclopyr ester product in oil applied to cut surfaces.  Drizzle applications with glyphosate, metsulfuron, or triclopyr only effective on treated parts of plants.  Apparently there was not enough translocation to kill the entire plant"  (Motooka et al., 2003).
