Landscape architecture involves applying artistic and scientific principles to plan, design, and manage both natural and built environments. It has various components, including aesthetic concepts of design elements like form, line, color, and texture, as well as physical components like plants, water, barriers, and buildings. Landscape design includes urban design, site planning for various uses, and design development with drawings, specifications, and plans. Professional landscape architects are responsible for planning and designing public and private developments, parks, gardens, and infrastructure while considering environmental and economic factors.
