What trees can be planted on the roof?

If the soil layer is thick enough, all the common trees planted locally can be planted. As it is a roof, it is suggested to plant some small trees. Such as red maple, osmanthus and so on. White orchids can also be planted. 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 materials used can be determined according to time and region.
