|These buildings provide examples of retro-fitted extensive green roofs in the Guangdong region and demonstrate a particular Sedum cultivar suited for conditions similar to those found in Hong Kong. These examples appear to be showcase examples for the Chinese Government.|
|Emulating the extensive green roofs that are seen in Europe and Germany is dependent on finding plant material|
which functions in much the same way (i.e. such as Sedums). Various local conditions (climate, typhoon winds, vigour of local invaders, etc.) make this a difficult exercise. However, a cultivar of Sedum lineare has been developed in Guangzhou which shows promising results in conditions very similar to Hong Kong. Sedums planted are 4 years old and show no signs of dying back or of being taken over by invaders. 95% roof coverage with soil depths of 30-40mm.
