Cultivation details

Requires a moist but well-drained soil in full sun. Plants are often found growing in clay soils in the wild. Suitable for the wild garden or other naturalistic plantings. In favourable situations this plant can self-sow to the point of nuisance. This plant is being evaluated by the Land Institute of Salina, Kansas, as an edible legume for growing with perennial grains in a non-tillage permaculture system. It is certainly worthy of more attention in this country, though the small seed size mitigates against its use. 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.


From seeds - pre-soak for 12 hours in warm water and then sow in a cold frame in the spring. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant them out into their permanent positions in early summer. If you have sufficient seed then it is probably worthwhile sowing some in situ in mid to late spring.
