Sedum album or White stonecrop, is a flowering plant of the genus Sedum in the family Crassulaceae. Sedum album is able to acclimate according to the environment. The left plant below, grew on top of the wall and therefore had access to less water and fewer nutrients; the right plant however grew at the bottom of the wall and therefore had greater amounts of water and nutrients. The plant at the bottom was therefore able to grow faster. The plant on top of the wall may be red due to plant lacking water and therefore having to synthesise carotenoids to protect it from photoinhibition. Sedum album is also able to switch between C3 carbon fixation and crassulacean acid metabolism (CAM) depending on the availability of water. CAM saves water as the stomata only open to allow CO2 to diffuse into the leaves at night when the temperature (and therefore evaporation) is lower.[1]
