Polygonum coriaceum is a semi evergreen herbaceous perennial with a spreading habit. Polygonum coriaceum is native to south west China and Tibet. Polygonum coriaceum is synonymous with Bistorta coriacea. In its native habitat it grows on grassy slopes and forest edges. Its mid green leaves are up to 14cm long. Its pink flowers appear on terminal spikes and are attractive to pollinating insects. Its roots are rhizomes, which aids its spread. Polygonum coriaceum is not widely available commercially in the UK.
