This is an introduced climbing plant which can reach 10 metres. It has small flowers which are 5-8mm long. These are 5-lobed white-tinged-greenish-pink and hang on short pedicels in branched, drooping clusters of 150mm long. The flowers sometimes turn bright pink as fruit develops. They are on climbing stems which are woody below. The leaves are oval-triangular with heart-shaped bases and long leaf-stalks. This is usually a casual garden discard and can be found on places such as railway embankments. It mainly grows in the S-East and the East of Ireland. Also known as 'Mile-a-minute' it belongs to the Knotweed family.
I first recorded this growing along the DART line in Dalkey, Co Dublin in 2010 when I also photographed it.
