In coastal habitats, it would be difficult to confuse sea beet with anything poisonous. It could be mistaken for one of the oraches, however, their leaves are not glossy and are more angular - they are also edible. Docks and horseradish (pictured) could also be confused, but sea beet's leaves are very smooth, glossier, and diamond or heart-shaped.

Use as a food The leaves are the edible part and can be collected all year. However, they are sweeter and softer in spring. They can be eaten raw (see hazards), pickled or cooked. Hazards When collecting from shorelines, be aware of any pollution such as sewage outlets. Also, most of the UK coastline is designated SSSI, so ensure you are allowed or have permission to forage.

Always stay safe when foraging. You need to be 100% sure of your identification, 100% sure that your foraged item is edible, and 100% sure that you are not allergic to it (it is good practice to always try a small amount of any new food you are consuming). If in doubt, leave it out!
