Lupinus angustifolius - L.

Common Name Blue Lupin, Narrowleaf lupine
Family Fabaceae or Leguminosae
USDA hardiness 7-9
Known Hazards The seed of many lupin species contain bitter-tasting toxic alkaloids, though there are often sweet varieties within that species that are completely wholesome[65, 76]. Taste is a very clear indicator. These toxic alkaloids can be leeched out of the seed by soaking it overnight and discarding the soak water. It may also be necessary to change the water once during cooking. Fungal toxins also readily invade the crushed seed and can cause chronic illness[65].
Habitats Cultivated and rocky ground on light acid soils [45, 50].
Range Europe - Mediterranean.

It can fix Nitrogen.
Suitable for: light (sandy) and medium (loamy) soils. Suitable pH: mildly acid and neutral soils and can grow in very acid soils.
It cannot grow in the shade. It prefers moist soil.

Edible Uses

Edible Parts: Seed
Edible Uses:

Seed - cooked[177]. Used as a protein-rich vegetable or savoury dish in any of the ways that cooked beans are used, they can also be roasted or ground into a powder. If the seed is bitter this is due to the presence of toxic alkaloids and the seed should be thoroughly leached before being cooked. The seeds of low-alkaloid varieties is used in making 'tempeh'[183]. The seed is rich in protein, though it is deficient in the amino-acid methionine[240]. The protein has a high digestibility (90%) and biological value(53%)[240].

Cultivation details

An easily grown plant, it succeeds in any moderately good soil[1]. Requires a sunny position[200]. Prefers a light acid soil[50] but tolerates adverse conditions. Dislikes limey soils[50]. Sometimes cultivated for its edible seeds, there are some named varieties that are low in the bitter toxic alkaloids. 'Uniwhite' is a low-alkaloid variety with a permeable seed coat. It has reduced pod-shattering[183] and so is easier to harvest mechanically. The blue lupin is a good companion plant for most vegetables[201]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.

Plant Propagation

Pre-soak the seed for 24 hours in warm water and sow in mid spring in situ[1, 200]. You may need to protect the seed from mice. Germination should take place within 2 weeks. The seed can also be sown in situ as late as early summer as a green manure crop.
