A kitchen garden is basically a garden that is placed close to one's kitchen to provide easy access to fresh herbs and vegetables for the cook. It is typically a garden that is set apart from other garden areas that grow ornamental things like inedible flowers. As far as another name for a kitchen garden, in France it is called "Potager" (jardin potager), but they often add ornamental plants to make the garden more visually appealing. We plant our "kitchen garden" with herbs and vegetables only, some add fruits or patterns that are aesthetically pleasing. Personally, I think a simple raised bed full of edible stuff for the kitchen is the best use of a kitchen garden.
