Lupinus luteus

Lupinus luteus, also known as the yellow lupin, is a species of lupin native to the Mediterranean region of Southern Europe. It is a member of the Fabaceae family, which includes other well-known plants such as peas, beans, and peanuts.

Description

Lupinus luteus is an annual plant that typically grows to a height of 1-2 feet. It has a deep taproot system, which allows it to thrive in poor, sandy soils. The leaves are palmately compound, with 5-9 leaflets arranged in a radial pattern. The flowers are yellow and are arranged in a dense, terminal spike.

Distribution and Habitat

Lupinus luteus is native to the Mediterranean region, including parts of Southern Europe and Northern Africa. It prefers sandy, well-drained soils and is often found in coastal areas. It is also commonly found in disturbed areas, such as roadsides and agricultural fields.

Uses

Lupinus luteus has been cultivated for centuries for its edible seeds, which are high in protein and dietary fiber. The seeds are also used as a source of lupin flour, which is used in baking and in the production of pasta. In addition, the plant is used as a green manure crop, as it is able to fix nitrogen from the atmosphere and improve soil fertility.

Cultivation

Cultivation of Lupinus luteus requires well-drained soil and full sun. The seeds should be sown in late spring, after the last frost. The plants are relatively drought-tolerant and require little maintenance once established.
