St John’s Wort grows up to 1.2m high with five petal yellow flowers. It invades open bushland and neglected areas and is a widespread invasive weed of temperate Australia. Ingestion of this plant can cause significant production losses and even death of livestock, as it contains hypericin, a compound that causes photosensitisation. It reproduces from crowns, lateral roots, and seed.
