Conringia orientalis (L.) Dumort.
Common Name: HARE'S-EAR MUSTARD
Coefficient of Conservatism: *
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Ad A-Forb

A Eurasian species, occasionally found in disturbed places such as railroads, cultivated fields and gardens, and vacant lots. First collected in Michigan in Marquette Co. in 1909. The petals may be so pale as to appear white, although they are usually said to be yellow.


Specimens of Brassica rapa may be keyed here if the pinnatifid lower and basal leaves are not collected or observed. Conringia has the buds and flowers exceeded by the tips of the fruits, even in plants almost finished with flowering while in Brassica rapa, the buds and flowers strongly overtop the developing fruits. As well, Conringia leaves are smoothly elliptic in shape, while the stem leaves of Brassica rapa (at least the larger) though entire and auriculate-clasping, are typically at least somewhat wavy-edged, and often have a “waist” or definite narrowing to the clasping base.
