Sea Bindweed Calystegia soldanella

This is one of my summer favourites, growing on our sandy shores and dunes, mainly on the north coast, particularly above Platte Saline and Arch bays. Another name for this strikingly beautiful plant is Beach Morning Glory, which seems very apt.

The large, funnel or trumpet-shaped flowers are pink with five equally spaced white lines which guide its pollinators, which include the Convolvulus Hawk-moth, towards the centre of the flower. At first glance, the pink and white form of Field Bindweed might be mistaken for this, its coastal cousin, but Field Bindweed is much smaller and without the glossy leaves.

It is a native plant belonging to the Convolvulaceae family but unlike the common bindweeds which climb it is usually prostrate and the leaves are completely different being large, dark green and glossy and kidney-shaped. They are also quite fleshy which aids moisture retention in their coastal habitat. Its stems often appear buried in the sand as it spreads by means of underground rhizomes and it is therefore useful in that it can help to stabilise dune systems under threat of erosion.
