Persicaria nepalensis (L.) Mill. is an annual herb occurring natively in South, East and Southeast Asia, having a range extending from Oceania to East Africa. Here we report the first Polish stand of this species, found in 2011 near Baligród (Western Bieszczady Mountains), followed by the discovery of two more stands in the surrounding area up to 2013. The floristic composition of vegetation impacted by P. nepalensis is presented, and the invasive potential and pathways of introduction of the species are briefly discussed.
