Thlaspi, or pennycress, [1] is a genus of herbs of temperate regions of the Eurasian continent. They occur in Central and South Europe, South-West Asia and two species are endemic to China. The Thlaspi has been proven to be a hyperaccumulator of heavy metals such as zinc and cadmium and therefore may be used in phytoremediation initiatives. [2]
 It is proposed that phytoremediation using Thlaspi caerulescens would be entirely feasible for low levels of cadmium.
