Distribution
Description
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.
Forms
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.
Cultivation and uses
Rosa sericea f. pteracantha is grown as an ornamental plant for its large, bright red thorns.
The plant, called se ba in the Tibetan language, has been used in traditional Tibetan medicine. In addition, silky rose hips were used as weights for measuring gold and silver in Tibet.[citation needed]
