Which plants are suitable for roof planting?

1) general principle: choose plants with short plants and shallow roots. Tall trees have deep roots and large crowns, but the roof is windy and the soil layer is too thin, which is easy to be blown down by the wind.

Therefore, roof gardens should generally choose plants with relatively low roots, drought tolerance, cold tolerance and barren tolerance. There are mainly the following categories.
