The Hedge Rose ( Rosa corymbifera ), and Busch-Rose or Wild Rose called, is a plant of the genus roses ( Rosa ) within the family of the rose family (Rosaceae). It must not be confused with the dog rose ( Rosa canina ), which is also often referred to as the hedge rose. It is native to Europe.
description
The hedge rose grows as a deciduous, broad- growing shrub and reaches heights of 2 to 3 meters. The spines are strong, hooked and usually longer than the broad base.
The alternately arranged leaves are unpaired pinnate with five to nine closely spaced leaflets. The leaflets are thin and with a length of 2.5 to 4 centimeters round-egg-shaped to elliptical with a blunt upper end, usually simply serrated, mostly hairy on both sides, at least on the underside on the nerves. The spindle is downy hairy.
The flowering time is in June. The flowers stand alone or in groups. Bracts are available. The mostly relatively long flower stalks are, like the flower cup, mostly hairy, but not glandular. The hermaphrodite flowers are 4 to 5 centimeters radial symmetry and five-fold with a double flower envelope . The five sepals are moderately pinnate, mostly glabrous on the back, rarely somewhat glandular, turned back after anthesis and lapsed. The five petals are white to pale pink. The stylus are free and they do not or only slightly protrude.
The rose hips, which are orange-red when ripe, have a length of 1.5 to 2 centimeters and are egg-shaped or spherical and usually smooth.
The number of chromosomes is 2n = 35.
Differentiation of similar species
The hedge rose ( Rosa corymbifera ) differs from the closely related dog rose ( Rosa canina ) in that it has larger flowers and is largely without thorns; the undersides of the leaves of Rosa corymbifera are hairy.
ecology
The hedge rose is a mesomorphic nanophanerophyte .
Pollination takes place by insects or by self-pollination and seed formation takes place without pollination.
The spread of the diaspores , it is the rose hips, occurs through digestive spread.
Occurrence
The hedge rose is a Eurasian-sub-oceanic to sub-Mediterranean floral element . Its range is roughly the same as that of Rosa canina , but it is less common overall; in the Alps it rises on the sunny side up to high-montane altitude . In Central Europe it is absent in certain areas, for example in the western lowlands, in the low mountain ranges with rock poor in lime, in the Alpine foothills and in the Alps.
The hedge rose thrives best on nutrient-rich , chalky or at least not strongly acidic soils , which should be stony-loamy; she prefers warm locations. It inhabits bushes and the edge of dry forests . It occurs in societies of the order Prunetalia.
Systematics
The first publication of Rosa corymbifera was in 1790 by Moritz Balthasar Borkhausen .
Rosa corymbifera belongs to the Caninae section in the genus Rosa .
There are several subspecies or varieties, which differ in the toothing of the leaves and greens and are sometimes viewed as a separate species. Other botanists consider all varieties of Rosa corymbifera to belong to the species Rosa canina .
- Rosa corymbifera Borkh. subsp. corymbifera
- Rosa corymbifera subsp. deseglisei (Boreau) Stohr (Syn .: Rosa deseglisei Boreau , Rosa dumentorum var. deseglisei (Boreau) M. Schulze )
use
The Wild Rose Pink corymbifera is used as base for the finishing of roses used. Rosa corymbifera is hardy to −29 ° C ( USDA zone 5 ).
Others
The blooming hedge rose often appears in soldier songs or folk songs, for example in Schön, the tail roses bloom .
