Gardening is the art of growing plants with the goal of crafting a purposeful landscape. Residential gardening most often takes place in or about a residence, in a space referred to as the garden. Although a garden typically is located on the land near a residence, it may also be located in a roof, in an atrium, on a balcony, in a windowbox, or on a patio or vivarium.

Gardening also takes place in non-residential green areas, such as parks, public or semi-public gardens (botanical gardens or zoological gardens), amusement and theme parks, along transportation corridors, and around tourist attractions and hotels. In these situations, a staff of gardeners or groundskeepers maintains the gardens.

Indoor gardening is concerned with the growing of houseplants within a residence or building, in a conservatory, or in a greenhouse. Indoor gardens are sometimes incorporated as part of air conditioning or heating systems.
