Updated: Jun 16, 2021

The genus known as Lupinus, commonly called Lupine, is truly a remarkable plant. It is a legume plant in the family Fabaceae, that grows well on poor soil and has tall stalks of incredibly beautiful and showy flowers. There are more than 200 species of lupine plants worldwide, a lot of which are very frost hardy, making them easily cultivated in almost all climates.

This can be done by simply soaking the beans in cold water for at least a week, changing the water daily. The alkaloids will dissolved into water over time and the beans will become softer and less bitter.

You can eat the beans raw, but some people prefer them slow cooked with some olive oil and garlic. They can also be pickled, added to salads, or cooked however you'd like with spices and herbs.
