On mobile sand, very close to the sea.

Pink with five white bands un-like Field Bindweed which, when not all white, is instead white with five pink bands.

Backlit with sunlight. Has a greenish yellow centre, usually too dark to discern.

With five bulky white stamens and a bulky stigma split in two which is almost the same colour, but ever so slightly creamier, it is totally unlike Field Bindweed.

More likely to have a roll-over surround than is Field Bindweed. Think loudspeaker cone. The sepal-like bracts number about five and are edged a rusty colouring. Note two as-yet un-opened buds top left and bottom right.

The leaves are kidney shaped and shiny and without hairs not dis-similar to those of Lesser Celandine.

Like the leaves of Lesser Celandine they have similar fainter green veins.

Easily mis-identified as : Field Bindweed but Sea Bindweed has the kidney shaped leaves that are both shiny and hairless, unlike Field Bindweed. Also, whereas Field Bindweed has white flowers (but sometimes white with pink stripes, it is the other way around with sea Bindweed, where the flowers are always bi-coloured, and are pink with white stripes. The end of the trumpet shaped flowers is more likely to be rolled over on Sea Bindweed, and the stigmas and styles are different: on Sea Bindweed both are club-shaped and white or cream, but on Field Bindweed the stigmas are white but pitch-fork shaped, and the anthers violet to blue. Sea Bindweed is prostrate and creeps along the ground, whereas most other Bindweeds climb upwards by entwining around thin objects.

Some similarities to : Hairy Bindweed, but that has hairy stems and is not prostrate like Sea Bindweed.

Slight resemblance to : Large Bindweed but that is much larger, and clambers upwards.

No relation to : Copse Bindweed nor to Black Bindweed [plants with similar names belonging to a diferent family, that of the Dock & Knotweed Family].
