Safety & Hazards

Although often used as an edible seed, there is a report that eating the seed of this plant can cause the disease 'Favism' in susceptible people[1]. Favism only occurs in cases of excessive consumption of the seed (no more details are given[PFAF]) and when the person is genetically inclined towards the disease[2].

Cultivation Details

HabitAnnual
GrowthFast

Prefers a fairly heavy loam but succeeds in a sunny position in most soils that are well-drained[3]. Grows well in heavy clay soils. Dislikes dry conditions[4]. The horse bean is winter hardy and can be sown in the autumn in many parts of the temperate zone. The autumn sown varieties are more susceptible to 'chocolate spot' fungus (which can be remedied by the addition of potash to the soil) but are more likely to escape damage from aphis[5]. 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[6]. 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

Seed - sow in situ in spring or autumn. The seed has a hard seedcoat and may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
