Fruiting St John's Wort. Some plants are taller than 1m with a stem diameter around 1cm at the base. The fruits are still closed as of 7 march 2022). One fruit head may contain > 10.000 seeds; each seed will last around 13 years in the soil seed bank.
FoMM sprayed StJW at this area till we run out of water to mix herbicide. We are now removing as many fruit heads as possible before the fruits split open to release their seeds.
