Broad bean is the same species as Faba bean (Vicia faba minor) and markets are also similar (i.e. mainly Middle East) but they have a wider Australian use, for example they are exported to Southern Europe and also South East Asia where they are roasted for use as snack food.
The plant is virtually identical to the Faba bean but has a slightly longer growing season and is therefore suited to regions of slightly higher rainfall (>500mm) to achieve the seed size. Prime growing areas are the south-west of Victoria and south-east of South Australia. Like Faba bean, they tolerate water logging and turn black when harvested.
