What plants can be planted on the roof for sun protection and heat insulation?

Planting Sedum sarmentosum on the roof can play a role in sun protection and heat insulation.

Sedum sarmentosum is a kind of grass with good drought resistance. It is used to plant on the roof. Soilless, can replace the traditional thermal insulation and waterproof protective layer. This kind of grass is very drought-tolerant. Even in hot summer, there is no need to water the dry roof.

Sedum sarmentosum can withstand drought for more than a month. This kind of grass grows on a 5 cm thick substrate on the roof, and can grow well only by natural precipitation, without artificial watering and fertilization.

Sedum sarmentosum has strong adaptability, can grow on a thin substrate without choosing soil, and has strong drought and cold resistance. In summer, the roof temperature is as high as 50-55℃, and the grass will not die if it doesn't rain for 20 days in a row.

Sedum sarmentosum can also absorb dust;

According to the research of South China University of Technology, Sedum sarmentosum can absorb 200 grams of dust per square meter a year, at the same time, it can release oxygen and improve the environment. According to the statistics of the Japanese Ministry of Forestry and the United Nations Environmental Protection Agency, if the urban greening rate increases by 1%, the temperature will drop by 1℃ and the dust will decrease by 15%. If the urban greening area exceeds 60%, the heat island effect will be greatly reduced.
