Sea bindweed
Sea bindweed is bound to the coast. It has adapted to sand drift, developing best on a buried flood mark. It is even resistant to incidental saltwater flooding but is sensitive to frost. Despite all these features, this winding vine grows mostly in sheltered areas in the Dutch dunes. Sea bindweed produces large seeds that are often spread by seawater. Because the plant needs another plant to produce fertile seeds, the stability of sea bindweed growth in the dune regions is strongly influenced by a cold winter.

In the Netherlands, sea bindweed is relatively rare and legally protected. It is only found locally in the delta and the wadden regions. It grows primarily in sheltered areas on humps of sand, in flood marks and in nooks and crannies in basalt dikes. Sea bindweed is found in moderate climates, in sheltered areas together with sea spurge, sea holly and marram grass. It also grows further away from the sea, among sea buckthorn bushes.
