Rosa sericea |
Rosa sericea, the silky rose,[1] is a species of flowering plant.
The closely related Rosa omeiensis is sometimes treated as a subspecies of R. sericea.
Distribution
[edit]It is native to south-western China (Guizhou, Sichuan, Xizang, Yunnan), Bhutan, northern India (Sikkim), Nepal and Myanmar; it grows in mountains at altitudes of 2,000–4,400 m (6,600–14,400 feet).
Description
[edit]It is a shrub growing 2 m (6+1⁄2 feet) tall and is often very spiny. The leaves are deciduous, 4–8 cm (1+5⁄8–3+1⁄8 inches) long, with 7–11 leaflets with a serrated margin. The flowers are 2.5–5 cm (1–2 inches) diameter, white, with (unusually for a rose) only four petals. The hips are red, 8–15 mm (5⁄16–19⁄32 inch) diameter, with persistent sepals, and often bristly.

[edit]There are four formae:
- Rosa sericea f. sericea
- Rosa sericea f. glandulosa T.T.Yü & T.C.Ku.
- Rosa sericea f. glabrescens Franchet.
- Rosa sericea f. pteracantha Franchet.
