About Grass pea
Lathyrus sativus, commonly known as grass pea or 'fôrflatbelg', is a fast-growing annual legume primarily cultivated for its edible seeds and as forage. It features climbing or sprawling stems with compound leaves and solitary or paired flowers, typically white, blue, or purple. This plant is ideal for vegetable gardens, as a cover crop, or for improving soil fertility.
Native range
Southern Europe, Western Asia, and East Africa
Care tips
It thrives in full sun for optimal growth, though it can tolerate partial shade. Regular watering is necessary to keep the soil moist, especially during flowering and pod development, but avoid waterlogging. It adapts to a wide range of soils but prefers well-drained and slightly alkaline conditions. A common mistake to avoid is late sowing, which can reduce yield and seed quality.
