Thlaspi arvense, known by the common name field pennycress,[1] is a flowering plant in the cabbage family Brassicaceae.

Description[edit]

A foetid, hairless annual plant plant up to 60 cm having round, flat, winged pods with a deep apical notch.[2]:421

Distribution[edit]

It is native to temperate regions of Eurasia, but is a naturalized introduced species throughout temperate North America and therefore has a circumpolar distribution. In the British Isles it is regarded as an archaeophyte (an ancient introduction).[3]

Ecology[edit]

Field pennycress is a weed of cultivated and wasteland.[3]

Edible uses[edit]

The field pennycress has a bitter taste; it is usually parboiled to remove the bitter taste. This is mostly used in salads, sometimes in sandwich spreads. It is said to have a distinctive flavour.

Use as a source of biodiesel[edit]

Pennycress is being developed as an oilseed crop for production of renewable fuels.[4][5] The species can be planted in the fall, will germinate and form a vegetative mass which can overwinter. In the spring, the oil-rich seed can be harvested and used as a biodiesel feedstock.

Research[edit]

Pennycress is related to the model plant species Arabidopsis thaliana. Researchers have begun studying the genetics of pennycress in order to improve its potential use as a biofuel crop. For example, the transcriptome of pennycress has been sequenced.[6]
