Charlock is an annual plant which grows on waste and arable ground and is found commonly throughout Ireland. It gros to a height of 150cm and bears dense, terminal clusters of flowers. These have 4 unnotched petals and sepals which are often down-turned. These racemes are borne on bristly, often dark red or purple stems.  The lower leaves are stalked with a large terminal lobe and the few small upper leaves are unlobed. The seeds are in short cylindrical pods and have prominent beaks. This plant belongs to the Cabbage family. 

 

I first found this plant at Cullenstown, Co Wexford in 2010 and photographed it near Hooh Head in the same county in 2012.
