Tree medic

Tree medic (Medicago arborea L.) is a perennial evergreen shrub belonging to the Fabaceae family. Unlike herbaceous alfalfa species, this plant develops a woody stem structure, typically growing between 1 and 3 meters in height. It is a hardy, long-lived legume that has been utilized for centuries in its native Mediterranean habitats.

The native range of this species covers the Mediterranean basin, where it thrives in rocky, well-drained soils and coastal environments. It is well-adapted to mild winters and hot, dry summers. In regions outside its natural range, cultivation is limited by its intolerance to severe, prolonged frost, requiring strategic site selection to avoid cold-air pockets.

Botanically, the plant is characterized by its trifoliate, silver-grey leaves and vibrant yellow raceme flowers. The root system is deep and extensive, which contributes to the plant's remarkable drought resistance. This structural complexity allows the shrub to stabilize loose soil, making it a functional plant for environmental restoration projects.

The agro-technical requirements for tree medic involve providing full sun exposure and alkaline, calcium-rich, porous soil. While the plant is drought-tolerant once established, supplemental irrigation during the seedling stage is crucial for ensuring vigorous root development. Periodic pruning is recommended to maintain a compact shape and stimulate fresh, nutritious foliage production.

Agricultural and landscape use includes providing a high-protein browse for goats and sheep, especially in semi-arid climates where other forage is scarce. Additionally, its aesthetic yellow blooms and evergreen nature make it a popular choice for xeriscaping. Common threats include aphids and various weevil species, while fungal root rot can occur if soil drainage is inadequate.
