Rosa filipes is a species of flowering plant in the rose family Rosaceae, native to western China, in Gansu, Shaanxi, Sichuan, Xizang, and Yunnan.
It is a deciduous climbing shrub, growing to 3–5 m, rarely up to 9 m tall. The leaves are pinnate, 8–14 cm long, with 5-7 leaflets. The flowers are white, 2–2.5 cm diameter with five petals, produced in large 15–30 cm diameter corymbs of up to 100 flowers. The fruit is a red 8–15 mm diameter hip. The plant is very vigorous, with stiff upright stems protected by large and frequent thorns. They allow growing stems to anchor on to tree branches and climb to a great height.
Cultivation and uses
It is grown as an ornamental plant in gardens, valued for its unusually large clusters of flowers compared to other roses, sometimes also for its size, and its ability to climb into trees.
The RHS Award of Garden Merit-winning cultivar 'Kiftsgate' was first noticed at Kiftsgate Court Gardens in the Cotswolds, but its origin is unknown.[1] The original plant dates from 1938 and the cultivar was named by Graham Stuart Thomas in 1951.[1] It is particularly vigorous, with clusters of scented flowers up to 45 centimetres (18 in) diameter, and tolerant of shade, a necessary attribute for a tree climber. The original plant of Rosa filipes 'Kiftsgate' is said to be the largest rose in Britain, measuring 80 feet (24 m) × 90 feet (27 m) × 50 feet (15 m) high.[1] The same official website claims that it have smothered three trees by its spreading habit.
