Persicaria maculosa

This native annual species that flowers during June to September, bears small spikes of tiny pink flowers that are arranged on long, drooping reddish coloured stems. It is also known as Heartweed, Lady's thumb, Redleg and Willow weed, with some of the names referring to its stems. It is very common on agricultural land and its seedlings can be abundant on land ploughed for the first time after 45 years. It occurs especially on moist soils in ditches, streamsides and other damp lowland situations but it is also quite common in dry areas where the ground has been disturbed.
