What kind of trees are suitable for planting on the roof?

Hawthorn and pomegranate are ok, mulberry is not suitable, and the first two are still shallow! Roof greening should not only choose plants with shallow roots, but also choose plants that are drought-resistant, barren-resistant, sun-resistant and wind-resistant. Generally, there are many shrubs and herbs, but few trees. The following plants can be planted on the roof: Pinus thunbergii, Podocarpus macrophylla, Buxus macrophylla, Buxus macrophylla, coral tree, palm, mosquito moth, Yucca, Gardenia, Bamboos, Sophora japonica, Cercis chinensis, Lagerstroemia macrophylla, Begonia, Chimonanthus praecox, Shoutao, Magnolia grandiflora, Magnolia geranium, Rhododendron and Magnolia grandiflora. Because I don't know my geographical location, I need to determine the materials used according to time and region. For roof gardens, there are also certain requirements for cultivation media. General light materials such as peat, coconut bran, perlite, vermiculite, sawdust, earthworm soil, etc. They are all selected, and some substrates, such as humus, can also be made by themselves. I hope I can help you.
