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 different family, that of the Dock & Knotweed Family].

Bindweeds have five fused petals forming an un-interrupted trumpet, but with five longitudinal creases.
