Landscape architects specialize in planning and designing outdoor spaces, including parks, gardens, streetscapes, and other public and private areas.

Unity in landscape architecture refers to the seamless integration of natural and built elements, creating a cohesive and visually pleasing environment.

Softscaping refers to the use of plants, trees, shrubs, and other vegetation to create a visually appealing landscape.

Xeriscaping is a type of landscape design that focuses on water conservation and sustainable practices, using drought-tolerant plants and efficient irrigation systems.

Hardscaping refers to the use of non-living elements like rocks, boulders, pavers, and water features to create structure and definition in a landscape.

Formal design in landscape architecture is characterized by geometric shapes, symmetry, and a structured, orderly arrangement of elements.

Naturalistic design in landscape architecture emphasizes the use of native plants and natural materials to create a landscape that mimics the natural environment.

Informal design in landscape architecture is characterized by asymmetry, organic forms, and a more relaxed, naturalistic arrangement of elements.

Environmental psychology is the study of the relationship between humans and their natural and built environments, including how these environments affect human behavior and well-being.

Rhythm in landscape architecture refers to the repetition of elements, such as plants, hardscape features, or colors, to create a sense of movement and unity in the design.

Sustainable design in landscape architecture emphasizes the use of sustainable practices and materials to minimize environmental impact, such as using native plants, reducing water usage, and incorporating energy-efficient features.

Contrast in landscape architecture refers to the use of different elements, such as colors, textures, shapes, and sizes, to create visual interest and emphasis in the design.

Screening in landscape architecture refers to the use of plants, fences, or other elements to create a sense of enclosure and privacy in a specific area of the landscape.

Proportion in landscape architecture refers to the proportional relationship between different elements in the design, such as the size of a tree compared to the size of a building, to create a sense of harmony and order.
