Dipsacus fullonum L. subsp. fullonum
Dipsacus sylvestris Huds.Dipsacus fullonum L.
common teasel, Fuller's teasel, teasel, wild teasel, wild teazel, wild teazle
Native to northern Africa (i.e. northern Algeria, Morocco and Tunisia), Europe (i.e. Ireland, UK, Austria, Belgium, Czechoslovakia, Germany, Hungary, the Netherlands, Poland, Switzerland, Albania, Bulgaria, Greece, Italy, Romania, Yugoslavia, France, Portugal, Spain, Moldova and Ukraine) and western Asia (i.e. Lebanon, Syria and northern Turkey).
Widely naturalised in south-eastern Australia (i.e. on the central and southern tablelands of New South Wales, in southern and eastern Victoria and in Tasmania).
Naturalised overseas in southern Africa, New Zealand, USA and South America.
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.
