In Europe they have a few varities that have been used for food.
I would buy some and see if any will overwinter.
This could be your feed when sprouted or cooked and mixed with fish oil.
You do have to process the edible lupines by soaking and cooking with several changes of water. The key to to soak and boil to remove any bitterness. If it tastes bitter you likely have some toxins still in the beans. As far as I know you CANNOT eat the wild Alaskan lupine.
Cover the beans with fresh water and set aside for 24 hours. During this period, drain, rinse, and replace water four times. They will swell and some will lose their peels. Drain and rinse the beans one more time and then cook them, in plenty of fresh water, between 2-1/2 to 3 hours. Remove a few and taste. If they are tender and absolutely not bitter anymore, they are ready to salt. - See more at:
