Abstract Background Ecological evolutionary and physiological studies have thus far provided an incomplete picture of why some plants become invasive therefore we used genomic resources to complement and advance this field. In order to gain insight into the invasive mechanism of Centaurea stoebe we compared plants of three geo-cytotypes native Eurasian diploids native Eurasian tetraploids and introduced North American tetraploids grown in a common greenhouse environment. We monitored plant performance characteristics and life cycle habits and characterized the .
