Sea Beet
Beta vulgaris

This annual/perennial plant trails low to the ground and sprawls over margins of salt marshes, old sea walls, grassy embankments and often close to the tide line on shingle. It has slender flower spikes, each with clusters of three tiny greenish flowers that appear during June and September. Even though this is a predecessor to the present Beetroot, apart from from the red-tinged, glossy leaves that are fleshy, there is little suggest that it is from the same family.
