What is a spreading form in plant design?

A spreading form in plant design refers to a plant that is low to the ground and spreads in width, typically characterized by its ability to cover a larger area horizontally rather than growing tall. This form is beneficial in landscape design for creating ground cover, filling in spaces, and controlling erosion. Spreading plants can also help to create a softer transition between different landscape elements and provide a lush appearance while reducing maintenance by minimizing the need for mowing or weeding in those areas.

The other forms mentioned, such as tall narrow plants or climbing plants, serve different purposes and have distinct growth habits that do not align with the definition of a spreading form. Understanding different plant forms is crucial for effective landscape design, as it aids in selecting appropriate plants to achieve desired visual effects and functional benefits within a garden or landscape project.
