Gunnera tinctoria is a gynomonoecious, clonal, perennial herb with large leafs native to Chile growing (up to 2 m tall). It became a very popular ornamental species in gardens and parks. The species produces large numbers of seeds and also spreads clonally by horizontal rhizomes. Typical habitats in Ireland include stream and river banks, coastal cliffs as well as disturbed areas, such as roadsides, quarries and ditches. Gunnera tinctoria is a strong competitor in its invasive range in Ireland.
