Interior landscaping is the practice of designing, arranging, and caring for living plants in enclosed environments.

Plantspec calls this 'interior landscaping' even though land is not literally being reshaped, 'Interior landscaping' is an appropriate term because indoor environments contain plains, angles, and horizons that are softened, accentuated or altered by the addition of plants and planters-thus landscaping the interior. Similar to outdoor landscapes, interior landscapes provide spaces with ornament, color, sculptural elements, focal points, and an overall pleasant environment.

In the trade, interior landscaping is also known as plantscaping and interiorscaping. Interior landscape firms will use one of the three terms or a combination. While interior landscaping is an accurate description of this specialty, plantscape and interiorscape are words that were invented at the birth of the interior landscape industry to define the trade.
