Plant-shaped three-dimensional flower bed plan

Quick answer：

Plant-shaped three-dimensional flower beds are landscape designs that utilize plants in a sculptural manner, creating elevated beds with a variety of shapes and heights. These designs often incorporate artistic elements and can be used in gardens, parks, or public spaces to enhance aesthetic appeal. A 'plane' in this context likely refers to a two-dimensional representation or plan of the flower bed design, which is used for layout and construction purposes.
