This one seems to have some sites baffled as they don't seem to realise that Plant is the name of the company not the pattern/range name.
Made by the Staffordshire firm of R.H. and S.L. Plant Ltd. at the Tuscan China Works at Longton. It's a beautiful pink china body, apparently called Peach Bloom and created by Tuscan themselves. They did several designs on the pink body but this one is lovely!
