Botanical name – Phaseolus. lunatus
Family – Fabaceae
Collection site – Sec-64, S.A.S Nagar (Mohali)
Habitat – fast-growing annual herbaceous vine, that becomes
weed in the wild. It rapidly colonizes degraded areas and nearby vegetation
forming dense thickets in forests, along trails, riverbanks, or fences. The seeds are edible
as green or in dry form. Beans are valuable in inter-cropping systems and are
important nitrogen fixing systems.
Habit – herbaceous vine – a twiner
