Lathyrus clymenum, commonly known as Spanish vetchling, is an annual herb in the Fabaceae family, native to the Mediterranean region, particularly in dry, open habitats such as grasslands and scrub areas. It is known for its climbing habit and typically reaches a height of up to 1 meter. Spanish vetchling produces delicate, pea-like flowers that are usually a striking combination of purple and pink, blooming from late spring to early summer. The plant’s seeds are encased in pods that are characteristic of legumes.

Spanish vetchling is valued for its high protein (25%) and dietary fiber (26%) content, which makes it a nutritious addition to diets. In cultivation, it thrives in well-drained soils with moderate moisture and prefers full sun exposure. While it is not commonly found in ornamental gardens, it has significant agricultural and culinary importance, especially on the island of Santorini, where it has adapted to the unique volcanic ash soil and climate. The seeds are harvested to prepare a traditional Greek dish called fava santorinis. However, the cultivation of Lathyrus clymenum can be challenging due to its vulnerability to strong winds and drought conditions, contributing to its higher market price. Gardeners should be aware of these potential cultivation issues, as well as the plant’s susceptibility to pests and diseases common to legumes, such as aphids and powdery mildew.CC BY-SA 4.0
