The National Mall in Washington, District of Columbia — The American Northeast (Mid-Atlantic)
Green Roof Plants
Soil depth on a green roof determines the types of plants that can be grown, and the depth of the US Botanic Garden roof will average just 3 inches. Green roofs with shallow soils are referred to as 'extensive', and those with soil at 6 inches or deeper are 'intensive.' Succulent plants, such as Sedum, are grown on green roofs for their ability to survive in shallow soils, with fewer available nutrients. In addition to succulents, the US Botanic Garden will trial many low-growing Mid-Atlantic native wildflowers and grasses that thrive in harsh environments.
