Pepperweed was called peppergrass but reason prevailed and since it is not a grass the name was changed. A member of the mustard family the seeds have a sharp taste when bitten. It is a winter annual forming a rosette in the fall and flowering in the spring. A problem in crops such as alfalfa and strawberries. Also widely found in newly seeded lawns.
