Lupinus pilosus, commonly known as blue lupine, (, ) is a species of flowering plant that is edible from the family Fabaceae that grows in Mediterranean scrubland.
The stem is long. Blooming from February to May, the species has white-coloured flowers which are long and pods in diameter. The legume is 3âÂÂ8 cm long. In Israeli farms, the Lupinus pilosus has blue flowers with a white vertical spot in the middle.
Around the South Tyrolean village of Altrei (Anterivo), L. pilosus was historically grown. The seeds were roasted and mixed with malt grains and infused in boiling water to produce a coffee-like but caffeine-free hot beverage, Altreier kaffee ("Altrei coffee"). Since 2006, a local initiative has been reestablishing L. pilosus cultivation in the Altrei region to revive this culinary specialty.
In the geographical region of Palestine, the plant is numbered among the few wild edible plants, but the seeds still require leaching in boiling water several times (with replacement of the water) for the seeds to become palatable. The seeds are then roasted in a skillet with a dash of water, salted, and eaten. The prepared seeds may be pulverized and mixed with wheat or sorghum flour for bread.
