Leaves 5.5–15 cm; stipules 20–25 × 3–8 mm, auricles flared or erect, 5–7 mm, margins usually entire, stipitate-glandular, surfaces glabrous, sometimes puberulent, sparsely sessile-glandular or eglandular; petiole and rachis usually (rarely) with pricklets, glabrous or puberulent to pubescent, sessile-glandular; leaflets 5–7 (on annual shoots), terminal: petiolule 6–20 mm, blade elliptic, ovoid, or ovate-lanceolate, 20–60 × 13–32 mm, firm, margins 1(–2+)-dentate-serrate, teeth 11–25 per side acute or obtuse, gland-tipped or eglandular, apex acute or obtuse, abaxial surfaces light green, glabrous or puberulent (on main veins), eglandular or sparsely to densely sessile-glandular, adaxial green, dull, glabrous or sparsely hairy. Inflorescences corymbs, 1 or 2(or 3)-flowered. Pedicels reflexed as hips mature, slender, (13–)20–28(–35) mm, glabrous, stipitate-glandular or eglandular; bracts 1–3, ovoid, 18–22 × 4–14 mm, margins entire, sessile-or short stipitate-glandular, surfaces glabrous, sometimes hairy, eglandular. Flowers 3–6 cm diam.; hypanthium ovoid to oblong, 5–8 × 4–6 mm, glabrous, eglandular, neck 1 × 2.5–3 mm; sepals spreading, often beak-capped, lanceolate, 20–33 × (2.5–)3–3.5 mm, tip 7–12 × 0.5–0.8 mm, margins entire, sometimes pinnatifid, abaxial surfaces glabrous, sometimes pubescent, eglandular or stipitate-glandular (north); petals single, rose pink to pale pink, (13–)22–25 × (11–)20–25 mm; ?stamens 75–100?; carpels 18–33, styles exsert 1 mm beyond stylar orifice (2 mm diam.) of ± flat hypanthial disc (3.5–4.5 mm diam.). Hips orange-red to bright red or blue-purple, globose to ellipsoid or urceolate, 10–23 × 9–11 mm, fleshy, glabrous, eglandular, neck 1–2 × 2–2.5 mm; sepals persistent, erect, often beak-capped. Achenes basiparietal, 14–25, tan, 4 × 2–2.5 mm.

Timberlines, larch-birch and pine forests, stony glades, grassy meadows, watersheds; at elevations from 1,500-2,800 metres. Betula forests, scrub, sunny slopes, roadsides; at elevations from 400-1,800 metres

The fruit can be eaten raw. They can be made into syrups or dried and used in soups and teas. They are also used for jams along with the petals. The seeds can be ground and used in baking or cooking.

The plants can be grown from seed, cuttings, suckers or by layering.
