Rosa fedtschenkoana
Encyclopedia
Rosa fedtschenkoana is a species in the plant genus Rosa
in the family Rosaceae
. It is native to the foothills of the Ala Tau
, Tian Shan
and Pamir-Alai mountain ranges in central Asia and northwest China. It is named after Olga Fedtschenko, a Russian botanist. It is deciduous
, forming a bushy and suckering shrub up to 2.5 metres high and as much across. The branches are covered in many prickles, many of which are fine and straight, but some are thicker and slightly hooked. The pinnate
leaves are pale greyish green in colour and have usually between 7 and 9 leaflets. The flowers are white, up to 5 cm across, and are borne singly or in small clusters at the tips of the branches throughout the summer months. The flowers' scent has been described as being "like 'Hovis' [brown] bread with a little blackberry jam". The flowers are followed by small, pear-shaped, bristly orange-red fruits.
Recent DNA
research has discovered that R. fedtschenkoana is one of the parents of the damask
group of garden roses (the other species involved being R. moschata
and R. gallica
). This accounts for the remontant
(repeat-flowering) nature of some damasks (the autumn damasks), as R. fedtschenkoana is one of the few remontant wild roses.
