Broad bean (Vicia faba) is a hardy annual legume grown for its edible seeds and pods, and also as a cover crop. Give it cool, well-drained rich loam in full sun and sow early, as it tolerates cold better than most legumes.
Family
Fabaceae (Pea & bean family)
Grows as
Annual
Light
Full sun
Water
Keep soil evenly moist, especially during flowering and pod set, and avoid waterlogging.
Soil
Rich loam; tolerates clay and somewhat saline soil but prefers good drainage.
Temperature
Hardy in cool conditions; grows best around 15–20 °C, with frost tolerance in young plants.
How easy
Easy
Safety
Mildly toxic: Raw or undercooked seeds contain lectins (phytohaemagglutinin) that can cause illness, which boiling destroys. Some people with favism (G6PD deficiency) can have a hemolytic reaction to the beans, and the seeds are rich in levodopa, which is unsafe for people taking irreversible MAO inhibitors.
Edible
Yes, some parts
Native range
as a cultigen from E. Medit.
Climate
temperate
About
Vicia faba, commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieties with smaller, harder seeds that are fed to horses or other animals are called field bean, tic bean or tick bean. This legume is commonly consumed in many national and regional cuisines.
Some people have favism, a hemolytic response to the consumption of broad beans, a condition linked to a metabolic disorder known as G6PDD. Otherwise the beans, with the outer seed coat removed, can be eaten raw or cooked. With young seed pods, the outer seed coat can be eaten, and in very young pods, the entire seed pod can be eaten.
How to grow it
Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. While their wild ancestor has not been identified and their origin is unknown, charred legumes of a possible wild-type progenitor have been identified at the Natufian site of the el-Wad Terrace. Carbonised domestic faba bean remains were discovered at three adjacent Neolithic sites in Israel's Lower Galilee (Yiftah'el, Ahi'hud and Nahal Zippori). Based on the radiocarbon dating of these remains, scientists now believe that the domestication of the crop may have begun as early as 8250 BCE.
Broad beans are still often grown as a cover crop to prevent erosion because they can overwinter and, as a legume, they fix nitrogen in the soil. The broad bean has high plant hardiness; it can withstand harsh and cold climates. Unlike most legumes, the broad bean can be grown in soils with high salinity, as well as in clay soil. However, it prefers rich loams.
Safety
Beans generally contain phytohaemagglutinin, a lectin that occurs naturally in plants, animals, and humans. Most of the relatively low toxin concentrations found in V. faba can be destroyed by boiling the beans for 10 minutes.
Broad beans are rich in levodopa, and should thus be avoided by those taking irreversible monoamine oxidase inhibitors to prevent a pressor response.
