Which landscaping element is described as spaces filled with plants and soil?

The term "softscape" refers to the living elements of landscape design, primarily consisting of plants, soil, and any natural components in the outdoor environment. Softscape includes a variety of vegetation such as trees, shrubs, flowers, and ground covers, which contribute to the aesthetic, ecological, and environmental aspects of a landscape. This terminology is essential in distinguishing it from hardscape elements, which are non-plant materials like pathways, walls, and patios.

In contrast, hardscape encompasses the hard, durable surfaces and structures within a landscape, whereas streetscape refers specifically to the visible elements in the streets and public corridors, focusing more on the interaction between buildings and the street. Water features include elements such as ponds, fountains, or streams and specifically deal with water components within the landscape. Thus, softscape is the most accurate choice for the description of spaces filled with plants and soil.
