Cultivation details

An easily grown plant, succeeding in any moderately good soil. It prefers a light acid soil but tolerates adverse conditions. Requires a sunny position. The white lupin is sometimes cultivated, especially in S. Europe, for its edible seed and also as a green manure crop. 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.


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.
