What plants are suitable for planting on the roof, which can shade the sun and grow well?

The natural environment of the roof is very different from the ground and indoor. High-rise buildings are windy, hot in summer and cold in winter, with plenty of sunshine, which is easy to cause drought. Therefore, shallow-rooted plants that are active, drought-resistant and cold-resistant should generally be selected, and they must also belong to low, wind-resistant and transplant-resistant varieties. Common ones are Pinus thunbergii, Podocarpus japonicus, Euonymus japonicus, Euonymus japonicus, Coral Tree, Palm, Mosquito Moth, Yucca, Gardenia, Bamao, Sophora japonica, Bauhinia, Lagerstroemia indica, Begonia, Chimonanthus praecox, Shouxing Peach, Magnolia grandiflora, Magnolia grandiflora, Tianzhu, Rhododendron, Peony and Camellia. The plant decoration of the roof can be cornice, two-eaves roof, flat roof and trapezoidal roof. According to different planting forms, potted flowers, leaves and fruits are often used, such as potted roses, oleander, osmanthus, colorful taro and so on. Or make all kinds of flower pots with hollow bricks, which are 25 cm high, lined with thick plastic film, with drainage holes at the bottom. The flower pots are filled with culture medium to plant all kinds of plants and flowers, such as a bunch of safflower, impatiens and aster. Wood flowers can also be planted in wooden barrels or large potted plants. Under the condition of not affecting the load of buildings, shade sheds can also be built to plant vines such as grapes, wisteria, lingxiao and radix aucklandiae. Parthenocissus tricuspidata and ivy can be planted on the walls of platforms and fences.
