Sea Bittersweet is a native perennial plant of the UK, typically found growing in shingle beaches and coastal areas, to a mature height of up to 40cm.

Bittersweet takes its name from the historically reported taste of the root which was described as initially 'bitter' but then 'sweet'. Note, however, that this is a poisonous plant not to be tasted or eaten. It contains solanine, which can cause vomiting, convulsions or even death. Sea Bittersweet is a maritime variety of Woody Nightshade.

Botanic classification and naming: Sea Bittersweet is a member of the Nightshade (Solanaceae) family. The genus name 'Solanum' identifies the plant as a Nightshade and its species name 'dulcamara' means 'bitter-sweet plant, coastal'.

Concerns: Woody Nightshade is a very toxic plant.
