Conringia orientalis

Conringia orientalis is a species of flowering plant in the mustard family known by the common name hare's ear mustard.[1] It is native to Eurasia but it is known elsewhere as an introduced species and sometimes a noxious weed. It is weedy in its native range and also in North America, where it is a widespread invasive species, especially in central Canada.[2]

It is an annual herb producing an unbranched erect stem 30 to 70 centimetres (12 to 28 inches) in height. The thick, waxy leaves are generally oval in shape, up to 9 centimetres (3+1⁄2 inches) long, and clasp the stem at their bases. The flower is enclosed in pointed sepals and has yellow, clawed petals about 1 centimetre (1⁄3 inch) long. The fruit is a beaded silique up to 13 centimetres (5 inches) long. The plant is known to be toxic to livestock.[2]
