Sophora flavescens, commonly known as Shrubby Sophora or Ku Shen, is a slow-growing evergreen shrub native to a wide range of habitats in Asia, including grasslands, open woodlands, and forest edges. It typically reaches up to 5 feet in height and is noted for its pinnate leaves and small, yellow, pea-like flowers that bloom in summer. The flowers are not particularly showy, but they do add a subtle charm to the plant’s overall appearance. The bark is yellowish-brown and can be used in traditional dyeing processes.

Shrubby Sophora is valued for its nitrogen-fixing ability, which enhances soil fertility, making it beneficial for ecological restoration projects. It is also widely used in traditional Chinese medicine, with its roots being the primary part utilized for their anti-inflammatory and antimicrobial properties. In cultivation, it is appreciated for its adaptability to various soil types, though it prefers well-drained conditions. It thrives in full sun but can tolerate light shade. While it is hardy to temperatures between -18 to -12°C, it may require protection in colder climates. Gardeners may use it as a specimen plant or in mixed shrub borders for its interesting foliage and medicinal history.CC BY-SA 4.0
