Green beans Facts
Green bean is herbaceous plant that belongs to legume family (Fabiaceae). It originates from Peru, but it can be found around the world today. People cultivate and eat green beans at least 7000 years. There are more than 130 varieties of green bean that differ in taste and in the color and size of pods. Green beans require direct sun, well drained soil and 21 to 27 degrees of Celsius for successful growth. This is the third most popular garden plant (after tomato and peppers). Unfortunately, it is often on a target of insects (which destroy leaves and pods) and it is prone to bacterial and viral diseases which decrease productivity of the plant.
