Persicaria elatior
Persicaria elatior, commonly known as tall knotweed, is a species of flowering plant native to eastern Australia. It was one of eleven species selected for the Save a Species Walk campaign in April 2016; scientists walked 300 km to raise money for the collection of seeds to be prepared and stored at the Australian PlantBank at the Australian Botanic Garden Mount Annan.
