Genus:Lathyrus

Species:

Family:Fabaceae

Lathyrus is a genus comprising both annual and perennial herbaceous vines characterized by their winged stems and vibrant flowers, belonging to the pea family. These plants are commonly utilized as animal fodder. For optimal growth, they should be planted in full sunlight and in rich, well-drained soil. Lathyrus readily climbs trellises and walls thanks to its tendrils, making it an excellent choice for cottage gardens or for cascading down slopes to prevent erosion. The term "lathyros" originates from Greek, meaning pea or pulse.

Regarding pests and diseases, Lathyrus generally faces no significant issues. However, it can occasionally attract aphids, mites, and pea moths. New plants may be susceptible to slugs and snails. Additionally, while rare, they can experience problems such as black root rot, leaf spot, powdery mildew, and rust diseases.
