description
Vegetative characteristics
The cinnamon-raspberry is an upright, deciduous, deciduous shrub with branches up to 2 meters long. The branches have no thorns and are densely covered with red stalk glands.
The alternate leaves are arranged in a petiole and a leaf blade. With a width of 15 to 25, rarely up to 30 centimeters, the relatively large leaf blade is three- to five-lobed with pointed, unevenly serrated lobes.
Generative characteristics
The flowering period extends from May to June (July). The hermaphroditic, slightly fragrant flowers are radial symmetry with a diameter of 4 to 5 centimeters and five-fold with a double flower envelope . The sepals are densely covered with red glandular hairs. The five free petals are purple-pink. The orange, hemispherical fruits rarely develop in Europe.
The number of chromosomes is 2n = 14.
Occurrence
The home of the cinnamon raspberry is eastern North America, from New Scotland west to Ontario and south to Tennessee . In Europe it has been cultivated as an ornamental shrub since the 17th century and is wild here in places, especially in south-east England, scattered in Germany and Austria (Graz), it is also found sporadically in Finland.
In its natural environment, the cinnamon raspberry grows in damp thickets and on the edges of forests.
use
The cinnamon-raspberry is often planted as a ground cover because of its large leaves and flowers. The fruits can be used for coloring (blue-violet).
The edible fruits (bad taste) are used as a food by some tribes of the North American indigenous people ( Cherokee , Iroquois ) as a remedy for cough, diarrhea and birth pains. An extract of the leaves of the cinnamon-raspberry is used by the Iroquois against kidney diseases. The roots relieve toothache.
