In short, any plant that can be eaten is a good one for a kitchen garden. Crops that are grown in the West typically include root vegetables, such as beetroot, potatoes, swedes and turnips. In addition, carrots and parsnips are popular choices. In terms of fruit, tomatoes are often cultivated, and some kitchen gardens are even large enough to accommodate small trees, such as apple trees, as well as bushes that produce berries, like gooseberries, for example. Also, herbs and squashes are relatively easy to grow in a kitchen garden.
