Rosa multiflora - Multifloral Rose

Rosa multiflora, also known as a multifloral Rose, is a multi -year, woody climbing plant from the family of rose plants (Rosaceae). This species originally comes from East Asia, especially from China, Japan and Korea, has spread worldwide, where it is often considered both as an ornamental plant and an invasive way.

Morphological characteristics

Rosa multiflora is a fast -growing, shrubby plant that can reach heights of up to 3 meters and widths of 6 meters. The branches are occupied with curved spines that represent effective climbing aid. The leaves are feathered and consist of five to nine elliptical, serrated petals.

The flowering period is late in spring until early summer. The flowers are small, with a diameter of about 1.5 to 2 cm, and are in dense, umbrella -rispine inflorescences. They are mostly white up to pale pink and smell light. After the pollination, which takes place through insects such as bees and flies, round to elliptical, red rose hips develop. These fruits are an important part of the food of many birds that contribute to the spread of the seeds.

Distribution and habitat

Originally native to East Asia, was Rosa multiflora introduced worldwide, especially as an ornamental plant, hedge plant and erosion protection. In many regions, especially in North America and parts of Europe, it has established itself as an invasive way. It grows preferably on nutrient -rich soils, in forests, on the side of the road and on open pastures.

Their ability to form densely thicknesses enables her to displace domestic plants and change entire ecosystems. At the same time, however, it offers habitat for many animal species and is an important source of food for pollinating insects.

Ecological and economic importance

The plant has both positive and negative effects on its environment. Their thick hedges offer protection for birds and small mammals, and the rose hips serve as food for wild animals. However, it can be problematic in agriculture because it overgrown pastures and reduces the productivity of usable space.

Use and cultivation

In the garden culture Rosa multiflora Estimated due to its robustness and its abundance of flowers. It is also used as a base for cultivated roses because it has a high tolerance compared to poor soil conditions and diseases. At the same time, due to its invasive properties, it is combated in many regions, for example through mechanical removal or the use of biological control methods such as the rose cicada beetle (Mecinus janthinus).

Hanging and management

While Rosa multiflora in her natural habitat, it is a significant challenge for the preservation of biodiversity. Strategies for containing include the promotion of native plant species, the removal of invasive stocks and the sensitization of the public for the risks of invasive plants.
