Description:  "Erect to trailing shrub up to 2 m or more in height.  Stems pilose, sparsely covered with prickles 1-4 mm long.  Leaves alternate, pinnately compound, 7-18 cm long, with 3-7 leaflets, leaflet blades ovate to lanceolate, 1.5-8 x 0.8-3.5 cm, acuminate to acute at the apex, rounded to truncate at the base; surfaces pilose to nearly glabrous; margins doubly serrate; stipules filiform, 6-10 mm long.  Inflorescence mostly of solitary, terminal or axillary flowers on a pedicel 0.5-3 cm long.  Calyx of 5 lanceolate sepals 1.4-2.5 cm long, tomentose, apex long-attenuate.  Corolla of 5 white, obovate petals 1-2 cm long.  Stamens many, free.  Ovaries many.  Fruit a subglobose, red, multiple fruit 2-3.5 cm long, easily detaching from the receptacle" (Whistler, 1995; p. 123).

"Shrubs or subshrubs; stems erect, arching, or trailing, 10-20 dm long, moderately to sparsely pilose, sparsely covered with recurved prickles 1-4 mm long with elongate bases.  Leaves pinnately compound, leaflets 7 or sometimes only 5 in upper leaves, broadly lanceolate, 1.5-8 cm long, (0.6-) 1-3 cm wide, the terminal one slightly larger, sparsely pilose to glabrate and also sometimes glandular-dotted, margins doubly serrate, petiolules 0.1-0.3 cm long, rachis, petiolules, and petioles pilose, rachis and petioles also usually covered with small recurved prickles, stipules filiform, 0.6-0.8 cm long.  Flowers solitary or sometimes 2-3, terminal or axillary; sepals lanceolate, 8-15 mm long, both surfaces finely tomentose, apex long-attenuate; petals white, obovate, 10-20 mm long.  Fruit red at maturity, subglobose, 2-3.5 cm long, easily deciduous from the receptacle"  (Wagner et al., 1999; p. 1110).

Habitat/ecology:  "Although roseleaf raspberry invades forest understories in some habitats, it is moderately shade intolerant, requiring partial sun to flower and fruit; it does best in full sun. Preferred habitats include natural and artificial openings in primary and secondary forest, such as tree-fall gaps, landslides, abandoned fields, neglected pastures, and roadsides. Roseleaf raspberry has a high moisture requirement, which usually means more than 1800 mm of mean annual precipitation and no severe annual droughts. The species usually grows at moderate to high elevations.  A variety of well drained to poorly-drained soils are colonized"  (Wildland shrubs of the United States and its territories).

Invades understory of moist forests. Grows to 2,200 m elevation in Tahiti (Meyer, 2000; p. 93). In Hawai‘i, "a common weed in disturbed mesic to wet forest, 60-1,730 m" (Wagner et al., 1999; p. 1110). "A nuisance in pastures and natural areas, where it displaces desirable plants and interferes with passage and use of the land"  (Motooka et al., 2003).  In New Caledonia, "cultivé à Koé en 1883; maintenant très commun près des pistes forestières sur schistes" (MacKee, 1994; p. 122).

Propagation:  Fruits spread by birds and rodents. "Stems root (layer) whenever they come in contact with the soil, which helps it fill in newly colonized habitat"  (Wildland shrubs of the United States and its territories).

Native range:  Asia, Australia.

Comments:  Very invasive in French Polynesia (Meyer, 2000; p. 93).

Control: 

Physical: Isolated plants may be grubbed out, but any remaining roots will sprout.

Chemical:  "Sensitive to triclopyr ester in water and very sensitive to triclopyr ester in a crop oil carrier, each applied by the drizzle method at 1 lb/acre.  HAVO staff reported control with foliar application of either glyphosate at 1% product or triclopyr ester at 1% product in water (Chris Zimmer, HAVO)"  (Motooka et al., 2003).
