Notes
Wild teasel (Dipsacus fullonum subsp. fullonum ) is regarded as an environmental weed in Victoria and Tasmania. While it is mainly a weed of pastures and roadsides, it sometimes also grows in natural communities and forms a large basal rosette of leaves in the early stages of growth. This rosette of leaves can cover a large area and shade other ground-dwelling plants nearby.
