Shrub to 1.2 m, sometimes reproducing vegetatively by elongated underground stems. Stems grey or brown-grey, longitudinally striate. Lower leaves biternate, with 9 leaflets; leaflets often reddish above, more or less ovate, base rounded, apex obtuse or acute, mostly entire but terminal leaflets sometimes shallowly 3-lobed, 4–12 × 2–8 cm, usually glabrous above, densely villous in axils of major veins beneath. Flowers solitary, terminal, April–May in China; bracts 2–4, leaf-like; sepals (2–)3(–4), yellow green, apex acute or caudate, the inner one largest, 2.5–3 × 2–2.5 cm; petals 5–9, spreading, pink, often with a pale red spot at the base, 3.5–5.5 × 2–3.1 cm; filaments pink; anthers yellow; disk entirely enveloping carpels at anthesis, red-purple, leathery; carpels 5, densely tomentose; stigmas sessile, red. Follicles ellipsoid, densely brown-yellow tomentose, 2–2.8 cm long. Seeds black, glossy, 6–8 × 5–7 mm. (Hong et al. 2001; Hong 2010)

Probably closely related to P. cathayana and P. jishanensis, this is one of the wild species to have emerged from the confusing mixture of hybrids, domesticated forms and probably wild plants once lumped under P. × suffruticosa. Pink flowered, with 9 leaflets, it is very rare and endangered in the wild, with four known populations, three of which are small and on cliffs (Hong 2010). Molecular evidence suggests that it has contributed to the hybrid woody cultivars (Zhou et al. 2014).
Plants under this name are in cultivation at low levels among peony specialists in Europe (Centro Botanico Moutan 2020) and North America (Bremer 2019). Seedlings offered in the European nursery trade are claimed to be low growing, to 50 cm, with red-brown tinted leaves, flowering late April to early May in Germany; however, they include white- as well as pink-flowered plants (Albiflora 2020; Gießler Päonien Kulturen 2020).
