The grass you can grow on your roof insulates against sound and prevents leaks, is free of pests and diseases, and is highly effective for treating bites, burns and scalds

Imagine: in the countryside, how beautiful it would be if your roof were completely covered with grass!

Some farmers would start to worry about the roof leaking. If you plant Sedum lineare, there is no need to worry at all. Sedum lineare is a succulent green grass species with excellent drought tolerance. Used for roof greening with soilless cultivation, it places an extremely light load and can replace traditional insulation layers and waterproof protective layers. Sedum lineare has super-strong drought tolerance; even in hot summer, on a dry roof it needs no watering, and its drought tolerance can last more than 1 month. Planted on a roof in a 5 cm thick substrate, Sedum lineare needs no artificial watering or fertilizing and still grows well using only natural rainfall. Even when the temperature drops to minus 10 degrees Celsius and the substrate and Sedum lineare are completely frozen into one mass, it is not killed by the cold; only the stems and leaves turn dark brown. The planting substrate does not need to be too thick; 5 cm is enough to meet its growth needs, because as a grass species with a shallow, fibrous, net-like root system, its roots are weak and fine, rooting shallowly, growing horizontally and forming a net-like distribution, with no ability to penetrate the waterproof layer and no damage to the roof structure.

Once Sedum lineare forms a turf, it is like a green carpet covering the roof. It can block damage to the roof from sunlight, wind, frost, rain and snow, and can insulate against heat, insulate against sound and prevent leaks. In addition, Sedum lineare can release oxygen, absorb dust and toxic substances from the air, eliminate noise and purify the environment.

There are many kinds of Sedum lineare with rich landscape effects. As of 2013, the introduced varieties of Sedum lineare included evergreen Sedum lineare, golden-leaf Sedum lineare, fine-leaf Sedum lineare and round-leaf Sedum lineare. Leaf colors include green, golden yellow and blue, and flower colors are mainly yellow, occasionally white and red. After being supplemented with other paving materials, it can form a colorful ecological landscape on the roof.

Sedum lineare basically has no pests or diseases and does not require control work. If you encounter problems while planting Sedum lineare, you can go to China's largest agricultural technology Q&A platform "Yunzhongyang", where many excellent agricultural experts are online in real time and answer questions for free.

Sedum lineare is produced in Yunnan, Sichuan, Guizhou, Guangdong, Hunan, Hubei, Gansu, Shaanxi, Henan, Anhui, Jiangsu, Zhejiang, Fujian, Taiwan, China and Jiangxi. It grows on grassy slopes in low mountains or flat land. It also occurs in Japan. The whole plant is used medicinally, with effects of clearing heat and detoxifying, dispersing blood stasis and reducing swelling, and stopping bleeding. It can be used for sore throat, hepatitis, carbuncles, sores and toxic swellings, venomous snake bites, shingles, and burns and scalds.

The temperature has dropped, and only Sedum lineare has not withered
