The term "keyhole garden" is also used in permaculture to describe a garden bed that has been laid out with one or more paths that dead-end rather than continuing through, in order to reduce the area of paths. Permaculture keyhole gardens tend to be wider and flatter than the African variety and do not generally incorporate a compost basket or compost pile built into the bed. The tall beds that incorporate compost are referred to as "banana circles" by permaculturalists.
