Species: A. Petiolata
Alliaria Petiolata, commonly referred to as "Garlic Mustard", is a herbaceous, biennial flowering plant. The leaves of Garlic Mustard are triangular or heart shaped, stalked, and simple. The leaf arrangement is alternate. The leaves of the plant have a garlicky taste, and the root has a taste akin to horseradish. The flowers are small, white and are found in button-like clusters. The flowers are radially symmetrical. The fruit of the plant is a silique--a slender pod 4-5.5 cm long.
General distribution and habitat
Alliaria Petiolata is remarkably expansive in its distribution. It is native to Europe, western and central Asia, northwestern Africa, the British Isles, north to northern Scandinavia, east to northern Pakistan and western China (Xinjiang). It was originally brought over to Northern America by Europeans in the late 19th century as a kitchen garden herb and salad green and has since rapidly expanded across the continent . It is now considered to be invasive. Within the United States, Alliaria Petiolata grows in man-made or disturbed habitats (such as roadsides), floodplains, forest edges, and forests. It can be quite aggressive in shady, moist areas and can form very dense colonies .
Alliaria Petiolata can be found in abundance along the main driveway to campus. As mentioned above, Garlic Mustard does extremely well along roadsides. It may be growing elsewhere on campus.
