Trifolium subterraneum, commonly known as subterranean clover, is a species of clover native to the Mediterranean region. It is a low-growing annual plant that typically reaches a height of 10-30 cm. The leaves are trifoliate, with each leaflet being oval-shaped and about 1-2 cm long. The flowers are small, pink or white, and arranged in clusters at the end of stems.

Subterranean clover is named so because it has an unusual characteristic of producing most of its growth and seed underground, which allows it to better withstand dry periods. It is also known for its ability to fix nitrogen from the air into the soil, which can improve soil fertility.

Subterranean clover is an important forage crop for livestock, as it is highly nutritious and palatable. It is also used in soil conservation, as its deep root system can help prevent soil erosion. It is commonly used as a cover crop in orchards and vineyards, as it can reduce weed growth and improve soil health.

Overall, Trifolium subterraneum is an adaptable and useful plant with a range of benefits in agriculture and soil conservation.
