Green Roof Plants

The types of plants you can grow on a green roof depend on several factors: the climate, sun exposure, water requirements, soil condition, etc.. These are the same things to take into consideration when planting a traditional garden. With a green roof, an additional factor is the depth of soil or growing medium on the roof. Some plants can do well in thin soils, and others require more depth for rooting. On a green roof, deeper soils mean more weight, which in turn means a stronger structure to support the roof.

When the outside temperature is 25 to…
