Caragana arborescens, commonly known as Siberian pea tree or Siberian peashrub, is a deciduous shrub belonging to the Fabaceae family. Native to Russia, China, and Mongolia, it has been widely cultivated in various parts of the world for its ornamental value and nitrogen-fixing properties. The plant is characterized by its upright, bushy form, reaching heights of 12 to 15 feet and spreading up to 10 feet wide.
The leaves of Caragana arborescens are composed of small, bright green leaflets that are arranged alternately along the stems.

The flowers are pea-like in shape and give way to slender, brown seed pods that persist through the winter, adding interest to the landscape.
Caragana arborescens is highly adaptable and can thrive in a wide range of soil conditions, including dry, sandy, or poor soils. Its ability to fix nitrogen through a symbiotic relationship with soil bacteria makes it a valuable plant for improving soil quality.
Due to its hardiness and resilience, Caragana arborescens is often used in windbreaks, hedges, and erosion control projects. It is also favored for its beautiful display of flowers and its ability to attract butterflies and pollinators. Additionally, the seeds of this shrub have been historically used as food by indigenous peoples, rich in proteins and carbohydrates.
In conclusion, Caragana arborescens is an attractive, nitrogen-fixing shrub known for its ornamental value, adaptability to various growing conditions, and ecological benefits.
