Laburnum anagyroides - common golden rain

Laburnum Anagyroides, known in German as a common golden rain, belongs to the Fabaceae family. This species is particularly valued because of its striking, hanging yellow flower grapes, which brought her the nickname "golden rain". Laburnum Anagyroides was scientifically described for the first time by the Swedish botanist Carl von Linné in the 18th century. This plant is closely related to other types of the genus Laburnum, especially with Laburnum Alpinum, and is often used in ornamental gardens and parks.

Morphological characteristics

Laburnum Anagyroides is a deciduous shrub or small tree that can reach a height of 7 meters. The plant has an expansive, open growth shape with smooth, greenish to gray -brown branches. The leaves are feathered and consist of elliptical to lanceolate leaves that reach a length of 3 to 8 centimeters. The leaves are dark green and brighter on the top, with a soft, velvety texture.

The flowers from Laburnum Anagyroides are bright yellow and arranged in hanging, grape -shaped inflorescences that can reach a length of 20 to 30 centimeters. The flowers are hermaphrodite and follow the typical butterfly flower structure of the Fabaceae family. The heyday ranges from May to June and is known for its intensive color splendor. After flowering, bean -like legumes develop, which are up to 6 centimeters long and contain several black, round seeds. The ripe fruits burst open when dry and sprinkle the seeds.

Ecological claims and distribution

Laburnum Anagyroides prefers sunny to partially shaded locations and thrives best in well -permeable, calcareous 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 distribution of Laburnum Anagyroides extends over southern Europe, especially in the mountain regions of the Alps and the Apennin. Due to its decorative properties, however, it is cultivated worldwide in gardens and parks.

Cultural and gardening importance

Laburnum Anagyroides has a long history of cultivation and has been used in garden art for centuries. The plant is often planted as an ornamental shrub in gardens and parks, often as a solitaire or in groups, to ensure a dramatic spring and early summer blossom. The common golden rain is also a popular plant for trellis forms and can be pulled via pergolas and arbors to create impressive flowering.

In art and literature, the golden rain is often used as a symbol of beauty and transience. Historically, however, the flowers and leaves were also feared because of their toxic alkaloids. All parts of the plant, in particular the seeds, contain the toxic cytisin, which can cause serious symptoms when swallowed.

Care and increase

The care of Laburnum Anagyroides is relatively uncomplicated. The plant only needs minimal care as soon as it is established. An occasional pruning after flowering 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.

The increase is mainly through seeds that can be sown in autumn or spring. The seeds need a cold stamping to break the germ rest. Alternatively, the plant can be increased by cuttings or finishing, although this is less common.
