Do not buy or plant large gunneras sold as Gunnera manicata in the UK. Genuine G. manicata is very unlikely to be present in UK cultivation, and plants offered under this name are highly likely to be Gunnera × cryptica, a hybrid of G. manicata and the invasive G. tinctoria. Gunnera × cryptica and G. tinctoria are banned from sale and must not be newly planted or cultivated. It is also an offence to plant or cause either plant to grow in the wild. Existing plants in gardens do not currently have to be removed, but gardeners must prevent their spread beyond the garden and dispose of all plant material correctly. See RHS advice on gunnera and invasive non-native plants for identification, management and disposal guidance
