Beach Knotweed

Beach Knotweed (Polygonum paronychia) is one of the common plants that can be seen on the beach among the dunes. This plant is fairly easy to identify by its narrow green leaves and small white flowers. The blooming season lasts at least a month, perhaps more.

As the Latin name suggests, the plant is part of the Knotweed family (Polygonaceae) so look for the swollen or distinctive joints along the stem. The flowers are not the spike like lots of other genera but rather distinctive small white flowers.
