Description
Lupinus albus graecus is a ANNUAL growing to 1 m (3ft 3in). See above for USDA hardiness. It is hardy to UK zone 7. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees. It can fix Nitrogen. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very acid soils. It cannot grow in the shade. It prefers dry or moist soil.
Edible Uses
Seed - cooked. 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 and mixed with cereal flours in making bread etc. If the seed is bitter this is due to the presence of toxic alkaloids and the seed should be thoroughly leached by soaking the seed and discarding the soak water before cooking them. An edible oil is obtained from the seed. The roasted seed is used as a coffee substitute.
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. 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.
Distribution
S. Europe - Greece.
Where It Grows
Coming Soon
Cultivation
An easily grown plant, it succeeds in any moderately good soil. Prefers a light acid soil but tolerates adverse conditions. Requires a sunny position. A form of L. albus with smaller seeds than the type. A deep rooting plant. 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. 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.
Propagation
Pre-soak the seed for 24 hours in warm water and sow in mid spring in situ. You may need to protect the seed from mice. Germination should take place within 2 weeks.
Other Uses
Nitrogen fixer. Dynamic accumulator.
