Hirschfeldia incana is characterized by its appressed fruits with a swollen beak usually containing a single seed. The fruits have been described as like an old-fashioned clothes peg (Rich 1991). Brassica nigra also has appressed fruits but the beak is seedless and not swollen.
The young inflorescences can be eaten like Broccoli.
