Lupinus
Lupinus, commonly known as lupin or lupine,is a genus of flowering plants in the legume family Fabaceae.They are widely cultivated, both as a food source and as ornamental plants.
The species are mostly herbaceous perennial plants 0.3–1.5 m tall, but some are annual plants and a few are shrubs up to 3 m tall. Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States. The flowers are produced in dense or open whorls on an erect spike, each flower 1–2 cm long. The pea-like flowers have an upper standard, or banner, two lateral wings, and two lower petals fused into a keel. The flower shape has inspired common names such as bluebonnets and quaker bonnets. The fruit is a pod containing several seeds that weight in average 24,8 mg each.
