lupin
n.n. a plant with large purple flowers that grows in dry areas. It is also the name of the seed inside the pod, which is a type of bean.
n. a tall, leguminous plant of the genus Lupinus, native to the Americas, characterized by large purple flowers and a pod containing edible seeds. Often used to refer to the seeds themselves, which are a significant source of protein in some cuisines.
The lupin plant grows well in dry, sandy soil.
Farmers in the Mediterranean often plant lupin to improve soil fertility because it fixes nitrogen from the air.
While the lupin is a staple crop in many arid regions for its protein content, its cultivation requires careful management to prevent the spread of invasive species in local ecosystems.
From Middle English lupyne, lupine, from Old French lupin, from Latin lupīnus (“pertaining to the wolf”), because of the wolf-like “fang” within the blossom. It has also been linked to an assumed depletion of nutrients in the soil.
