2. Use landscape plants to create artistic conception for landscape design.

3. Use the spatial variation of garden plants to design the landscape.

4. Landscape plants are sequential landscapes used to express landscape design.

1. Landscape design using landscape plants to express regional characteristics. Taking advantage of the differences in garden ecology and climate, plants present regional landscapes. For example, palm trees, king coconuts and betel nuts create tropical scenery in the south, while lush pine and cypress trees and tall deciduous trees show rugged scenery in the north. After long-term plant cultivation and application, plant landscapes with local characteristics have been formed in various places, which are integrated with local culture. Even some plant materials have gradually evolved into symbols of a country or region, such as old cherry blossoms, tulips in the Netherlands, maple trees in Canada and Chengdu in China. In particular, we should cherish this feature, actively use plant materials with local characteristics, create plant landscapes, carry forward local culture and cultivate people's sentiments. Creating artistic conception with garden plants is a typical landscaping style and valuable cultural heritage of traditional gardens in China.

2. Use landscape plants to create artistic conception for landscape design. Using garden plants to create artistic conception is a typical landscaping style and valuable cultural heritage of traditional gardens in China. By skillfully using the personalized contents of various plant materials endowed by China culture, we can appreciate the formal beauty and artistic conception of plants, and achieve the ideal state of harmonious coexistence between man and nature. China gardens are good at applying plant themes, expressing the artistic conception of gardening, taking flowers and trees as the landscaping theme, creating scenic spots or building themed gardens. In the classical garden landscape, there are many examples of plants as the main scenery, such as Xinghua Chunting, Liulang Wenying, Quyuan Fenghe and Wu Tong Bookstore in Yuanmingyuan. In central chengde mountain resort, plants such as Banba, Lotus, Magnolia, Begonia, Willow, Bamboo and Indus are used as materials to create plant garden landscape. In the planning of China Modern Park, there are many successful examples of learning traditional technology. The new attractions of Beijing Zizhuyuan Park include early spring bamboo garden, fine green wave, late autumn of Qu Yuan, art garden, new bloom, drinking pavilion, wind and summer night. The scenic spots in changfeng park include Camellia Pond, Baihua Pavilion, Muxiang Pavilion, Sleeping Lotus Pond and Matsuzaka Plum Garden. Among all kinds of park attractions built in China, there are characteristic botanical gardens such as rose garden, peony garden, bamboo garden, magnolia garden, rhododendron garden, osmanthus garden, brown shelf garden, machine tree garden, aromatic garden, rock botanical garden, herbaceous garden and Chinese herbal medicine garden.

3. Use the spatial changes of garden plants for landscape design. The plant itself is a three-dimensional entity, which is the main component of the spatial structure in landscape architecture. Trees with tall leaves are regarded as single buildings, all kinds of vines cover scaffolding and roofs, hedges are trimmed like walls, and flat lawns are laid on the level ground. Therefore, plants, like other buildings and landscapes, have the functions of forming space, separating space and guiding space change. The spatial change of plants can be realized by borrowing scenery, blocking scenery and other means. And it can also produce "steps" through the changes of people's sight and visual environment.

4. Landscape design is to use landscape plants to express sequential landscape. Garden plants will show different seasonal characteristics with the change of seasons, such as bloom in spring and shade in summer; Autumn leaves are intoxicating and fruitful; It snows in winter, and the branches are covered with insects. This ups and downs of life rhythm provides conditions for us to create a sequential landscape of garden seasons. We can plant plants with different flowering periods according to the seasonal changes of plants, so that different landscapes can be produced in the same place at different times, giving people different feelings and understanding the seasonal changes. Of course, you can also show the sequential landscapes in the form of theme parks, such as: building a spring garden, planting spring flowers, magnolia, begonia, cloves, peach blossoms, winter jasmine and so on. Show the colorful beauty of spring.
