Rosa willmottiae

Rosa willmottiae, Miss Willmott's rose[1] or Willmott's rose,[2] is a species in the genus Rosa in the plant family Rosaceae. It grows at an altitude of 2,300–3,150 metres (7,550–10,330 ft) in dry valleys in western Sichuan, China.[3] It forms an arching deciduous shrub 2–3 m (6 ft 7 in–9 ft 10 in) high, and as much across. The branches are covered in many straight prickles. The pinnate leaves typically have 7 to 9 small bluish-green leaflets which emit a pleasant fragrance when bruised.[4] It was introduced to western cultivation by Ernest Wilson in 1904 and was named after the collector and horticulturist Ellen Willmott. The flowers are small (25–40 millimetres or 1.0–1.6 inches), lilac-pink, and are borne on short laterals all along the length of the branches in late spring/early summer. The hips are small, becoming orange-red and losing their tips when ripe.
