Vicia articulata
Safety & Hazards
The seeds contain the anti-nutritional compound L-canavanine, a competitive inhibitor of arginine decarboxylase. This is removed by soaking the seeds in water prior to cooking and discarding the soak water[1].
Cultivation Details
Species in this genus generally succeed in any well-drained soil in a sunny position if the soil is reliably moist throughout the growing season, otherwise they are best grown in semi-shade[2]. Succeeds in poor and sandy soils[1]. Established plants are drought resistant[3]. Producing a seed somewhat similar to lentils, the plant is said to be more resistant to fungal diseases and bird attacks[1]. The plant is mainly self-fertilizing, with insects as occasional pollinators[1]. 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[4]. 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. An autumn sowing in situ might also succeed. 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.
