Are native or non-native species grown on a green roof?
A green roof is not a native environment due to the amount of heat, exposure to the sun, wind, and rain the plant systems must endure in order to survive in such a habitat. Sedums are native to coastal, alpine, and desert climates and are therefore more adapted to changing weather conditions which can be harsh at times. They are ground covering plants by nature and do very well in a green roof environment. Herbaceous native plants tend to require irrigation to survive. In some installations, native species can thrive if given the correct conditions and proper care.
