What are the vertical greening plants?

In view of the limited space of urban ground greening, in order to alleviate the urban heat island effect and meet the needs of urban landscape on the basis of increasing urban green quantity, it has become one of the important ways to increase urban green coverage and improve urban ecological environment by using climbing plants for vertical greening and building outdoor vertical greening plant walls. So how to choose plants suitable for outdoor vertical greening walls?

When choosing the plant species for outdoor vertical greening plant wall, priority should be given to the species with fast growth, evergreen seasons, high ornamental value and rapid landscape effect. Plants should use low shrubs, lawns, ground cover plants and climbing plants as much as possible, which is not only conducive to reducing construction and maintenance costs, but also can adapt to the limited thickness of roof soil matrix. In addition, it is not advisable to choose plants with strong root penetration to prevent plant roots from penetrating the building structural layer.

Outdoor vertical greening wall can choose greening plants:

1. Evergreen plants: Podocarpus, Pinus pentaphylla, Platycladus orientalis, Buxus macrophylla, Buxus macrophylla, Scarabs, Holly, Bromus, Mosquito Mother, Mahonia latifolia, Mahonia hupehensis, Ilex angustifolia, Lonicera stolonifera, etc.

2. Lianas: honeysuckle, yellow heart, spring jasmine, fragrant tanchun, ivy, periwinkle, grape, trachelospermum, wisteria, wisteria, Celastrus orbiculatus, Euonymus fortunei, kiwi, honeysuckle, passion fruit, cucumber, loofah, dill, morning glory, kudzu root, etc.

Vertical greening plant wall, climbing vertical greening plant varieties are Pterocarya stenoptera, Petunia and honeysuckle. The preferred vertical greening plant varieties are lantana camara and wedelia australis.

It is worth noting that the golden dragon with five claws is an alien invasive species, and Petunia grows vigorously. Without human intervention, these two plants grow wildly, which will affect the growth of surrounding plants and even cause serious ecological damage. Therefore, in the practical application of vertical greening of these two plants, their growth environment should be strictly controlled, and artificial pruning and cleaning should be carried out regularly to avoid their growth flooding, which is also conducive to maintaining a more lasting and stable vertical greening landscape.

In addition to the above recommended plant varieties suitable for outdoor plant walls, we can also make full use of plant resources according to the actual climatic conditions and choose other plants according to local conditions. As long as the plants conform to the principles of drought resistance, heat resistance, cold resistance, strong light resistance, strong wind resistance and less pests and diseases, they can be used as plant auxiliary varieties for vertical greening plant walls for reasonable planting.
