Species Details

Black Mustard is a very rare, native annual of waysides and waste places, which occurs scattered throughout Derbyshire from Potluck House (SK1377) and Sheffield (SK3383) in the north to Long Eaton in the south (SK4933). Previously it occurred over much the same area but grew more in rural areas where it occurred on stream banks and arable land. Recently it has occurred more in built-up localities that seem to be its preferred area of occurrence now.
