Classification
editRosa sempervirens L. is most closely related to Rosa phoenicia Boiss. and Rosa arvensis Huds..[1]
It was used repeatedly as parent for hybrids produced by Henri Antoine Jacques, gardener to King Louis Philippe I of France.[2]
Habitat
editIt is an evergreen shrub[3] mostly growing in maquis or in sheltered valleys [citation needed]. Its distribution encompasses mainland Greece, some Aegean islands (including Crete), the Adriatic coast of the Balkans, Italy, the islands in the Western Mediterranean, some coastal areas of the Iberian peninsula and France (up to 700 m in the Maritime Alps, and northwards up to the southernmost parts of Brittany), in the north of Morocco and Algeria, and in more isolated instances in the Atlas Mountains and in European Turkey.[4][1]
Description
edit
Rosa sempervirens leaves are glossy, compound-pinnate and evergreen. It is a bushy shrub that can reach 1.5 meters high, growing in hedges or forming thickets. Climbing forms can reach 3.5 m in height. The stems bear few, slightly curved prickles.
The imparipinnate leaves generally have five leaflets, sometimes seven. The leaflets, lanceolate oval, shiny on their upper surface, glabrous, with tight edges, are 2 to 5 cm long. These relatively leathery, dark green leaves persist much of the winter.
The white, simple, slightly fragrant flowers, 3 to 5 cm in diameter, are grouped together in sparse corymbs. They bloom in spring and early summer from May to July, or in spring and early summer. The fruits, globular or ovoid, orange-red when ripe, are about 1 cm long.
