vegetable garden, garden that exists to grow vegetables and other plants useful for human consumption

vegetable garden (also known as a vegetable patch or vegetable plot) is a garden that exists to grow vegetables and other plants useful for human consumption, in contrast to a flower garden that exists for aesthetic purposes.

 It is a small-scale form of vegetable growing. A vegetable garden typically includes a compost heap, and several plots or divided areas of land, intended to grow one or two types of plant in each plot. It is usually located to the rear of a property in the back garden or back yard. 

Many families have home kitchen and vegetable gardens that they use to produce food. In World War II, many people had a garden called a 'victory garden' which provided food to families and thus freed up resources for the war effort.
With worsening economic conditions and increased interest in organic and sustainable living, many people are turning to vegetable gardening as a supplement to their family's diet. Food grown in the back yard consumes little if any fuel for shipping or maintenance, and the grower can be sure of what exactly was used to grow it. Organic horticulture, or organic gardening, has become increasingly popular for the modern home gardener.
There are many types of vegetable gardens. The potager, a garden in which vegetables, herbs and flowers are grown together, has become more popular than the more traditional rows or blocks.
