What part of the plant is green beans?

answer 2 Green bean plants come in several styles, dwarf, <300mm high; to scarlet runner, > 2.5m tall. Their pod lengths run from about 100mm to c400mm respectively.

In all cases they are the seeding part of the bean plant, the genera Phaseolus.

Green beans are not necessarily coloured green, the adjective may mean that they were picked before they were fully ripe, and this is the common condition and means that the whole pod and contents may be eaten.

Dwarf beans in my garden are coloured green, purple, and yellow.

Their flower has a long tube, and locally the bumble bees just drill a hole through the tube wall to get at the nectar, which results in sterile flowers, and no beans.

Broad Beans differ from the other common beans in having a broad ( 30mm wide) pod, and the beans themselves are up to 40mm long, nestled in a fluffy bed in the pod. The bean itself is covered with a green-grey skin, and if this is removed, the green bean inside tastes quite different. In this condition it makes a nice addition to a salad. Many folk do not like the taste of broad beans, but the slight bitterness is due to the skin, not the bean.
