Neslia paniculata
Neslia paniculata (commonly called ball mustard) is a plant species in the family Brassicaceae. The name comes from the ball-shaped fruits that contain a single seed within an indehiscent fruit coat.{{cite journal |last1=Royo-Esnal |first1=Aritz |last2=Gesch |first2=Russell W. |last3=Necajeva |first3=Jevgenija |last4=Forcella |first4=Frank |last5=Edo-Tena |first5=Eva |last6=Recasens |first6=Jordi |last7=Torra |first7=Joel |title=Germination and emergence of Neslia paniculata (L.) Desv. |journal=Industrial Crops and Products |date=March 2019 |volume=129 |pages=455–462 |doi=10.1016/j.indcrop.2018.12.030 }} It is an annual where the seeds germinate in autumn to winter and grow into a flattened rosette of leaves that develop vertical flowering stems in the spring. These can be up to 1 metre tall. The flowers open in late spring/early summer and the seeds are mature by summer.{{cite web |title=Ball mustard |url=http://www.herbiguide.com.au/Descriptions/hg_Ball_Mustard.htm |website=Herbiguide |publisher=Herbiguide Pty Ltd |accessdate=1 July 2019}}
It is a native plant of temperate regions of Eurasia.{{cite web |title=Neslia paniculata (L.)

Its seed pods can contaminate harvests of mustard and rape/canola, even after cleaning. At the other end of the spectrum, within some its original region it has become a threatened or rare arable plant as a consequence of improved agricultural practices.
