Native to the coastline of western North America, Seashore lupin grows no more than 30 cm tall, not to mention that it boasts purple flowers. As for the fruit, it is a hairy legume pod containing up to 12 seeds. The root of this variety, which is edible, can be dried and roasted, especially since it has a sweet flavor to it, almost like sugar, not to mention that it’s rich in starch. As a matter of fact, eating lupin beans adds nutritional value to your diet because they come packed with fiber, protein, B-complex vitamins and essential minerals. Protein, for instance, aids in new cell growth, supports tissue repair and maintains immune system function.
