About
Arabidopsis lyrata, the lyrate rockcress, is a species of flowering plant in the family Brassicaceae, closely related to the model organism Arabidopsis thaliana.
Where it grows
Arabidopsis lyrata is found largely in subarctic or subalpine environments with thin soils, such as rock faces, eskers and talus slopes, or exposed coastal zones. Individual plants may form solitary rosettes, and are able to reproduce asexually through clonal patches. Lastly, Arabidopsis does not survive in agro-ecosystems in which weeds are rampant; it performs best under low competition and therefore has a life cycle that depends on germination, growth, and the setting of seeds in a very short amount of time before other species of plants can prevent light access.
