Rosa Xanthina - yellow rose

Rosa Xanthina, known as a yellow rose in German, belongs to the Rosaceae family. This species is particularly valued because of its bright yellow flowers and robustness. Rosa Xanthina was described in the 19th century by the botanical work by Adrien René Franchet and Ernst Rudolf von Rule. The genus Rosa comprises about 150 to 200 species that are widespread worldwide in moderate and subtropical zones. Rosa Xanthina is at home in the mountain regions of China and was discovered there for the first time.

Morphological characteristics

Rosa Xanthina is a deciduous shrub that can reach a height of 2 to 3 meters. The plant has an upright, bushy growth shape with slim, thorny branches. The thorns are mostly bent and distributed at regular intervals along the shoots. The leaves are feathered and consist of 5 to 11 elliptical to lanceolate leaves that have a length of 2 to 5 centimeters. They are dark green on the top and lighter and slightly hairy on the top.

The flowers of Rosa Xanthina are arranged individually or in small groups and have a diameter of 4 to 6 centimeters. They are bright yellow and have five petals and numerous golden yellow stamens that form a striking contrast. The flowering period ranges from April to June, with the flowers exuding a pleasant, mild fragrance. After flowering, spherical to egg-shaped, orange-red rose hips develop, which have a diameter of about 1 to 1.5 centimeters and contain several seeds.

Ecological claims and distribution

Rosa Xanthina prefers sunny to partially shaded locations and thrives best in well -permeable, slightly acidic to neutral soils. The plant is relatively resistant to dryness and can adapt to a variety of soil types, including sandy, loamy and stony floors. It is hardy and can withstand temperatures up to -20 ° C, which makes it suitable for cultivation in moderate climate zones.

The natural spread of Rosa Xanthina extends over the mountain regions of northern and central China, including the provinces of Gansu, Shaanxi and Sichuan. It typically grows in light forests, on forest edges and on open slopes. Because of its decorative properties and its robustness, it is also cultivated in gardens and parks in other parts of the world.

Cultural and gardening importance

Rosa Xanthina has a long history of use in garden art and landscaping. The plant is often planted as an ornamental shrub in gardens and parks, often as a solitaire plant or in groups, to ensure a striking floral splendor. The yellow rose is also known for its robust properties that make them resistant to diseases and pests.

In landscape design, Rosa Xanthina is appreciated because of her ability to grow quickly and to form dense shrubs that are both aesthetically appealing and practical as privacy protection. Your bright yellow flowers bring color to every garden and are a popular attraction for pollinators such as bees and butterflies.

Care and increase

The care of Rosa Xanthina is relatively uncomplicated. The plant only needs minimal care as soon as it is established. An occasional pruning promotes a thicker growth shape and removes dead or damaged branches. The plant should be irrigated during longer dry periods to avoid stress, especially in the first years after planting. Regular fertilization with a balanced rose fertilizer supports growth and flower formation.

The propagation is mainly done by seeds or cuttings. The seeds often have to be subjected to cold traification to break the germ rest, which means that they have to be exposed to a period of low temperatures before they can germinate. Coats are taken in late spring or early summer and rooted in a damp, well -permeable substrate.
