Sweet Lupin Seeds

I'm interested in growing sweet lupins, particularly a variety (guessing commercial only/patented "australian sweet lupins" which require no soaking or have no alkaloids.

I'm still googling, but finding one's that still need soaking, etc. And while soaking like other beans is not a deal breaker, it'd be nice to not have to.

Thus me asking for any help finding seeds.

Thank you!

This may not be super helpful, as I have NOT found any that don't require soaking. I just bought some on Etsy from PlantifulFarm, but I am not planning to consume them - more of a decorative cover crop. I have also sprouted (other) legumes from Rancho Gordo, so you may be able to buy some packaged as food? Out of caution, I would rather soak (at least some) than trust that they don't have to be soaked.

This is the description from the Etsy seller
"Lupini Bean (Lupinus albus): A nutritious and ancient legume perfect for adventurous gardeners. Unlike other beans, lupini beans have a distinctive firm texture and require boiling and soaking over several days to remove alkaloids. Wait until the pods are dry and rattle when shaken, then harvest and dry further. Use in Mediterranean-inspired dishes, such as hummus or stews. Or grind into flour for use in baked goods. Or dry roast for a protein-rich snack. Cooking time is longer than other beans, but the nutty flavor and high protein content make it worth the wait. Lupini beans have a protein percentage even greater than soybeans! Lupini beans also fix nitrogen in the soil, making them a great companion plant. Try this unique and rewarding legume in your garden!"
