Sea Beet or Wild Sea Spinach

Updated: Jul 15, 2023

The Sea Beet or Wild Spinach also known as the Sea Spinach is a distant relative of the many foods that are cultivated today including Chard, Beetroot and Sugar Beet.

This is a UK coastal plant that I think you should become very familiar with as it is simply delicious. The sea beet or beta vulgaris maritima is a very common species of plant that lives around our coasts. It can be found all around the UK coastline and can be found living on the upper beach, shingle beaches or waste land close to the sea.

Near me, you can find it both sides of the sea wall, happily growing in grassland, in the range of winter storm spray. The plant is extremely common and it amazes me why it isn’t used more often in the kitchen, it grows profusely, sometimes the plants or areas covered by sea spinach are something to behold as it quilts whole areas of ground. The plant isn’t a relative of the spinach that we consume so readily today but in my eyes it is a far superior alternative that offers everything that cultivated spinach does not.

What does Sea Beet taste like?

Maybe this is just me but when I eat spinach I am always under whelmed with its texture especially that of cooked spinach, the leaves of the sea beet are large and thick with a good stem running up the centre of the leaf. The thick leaves make the leaves feel more satisfying and filling and due to the robustness of the leaf they are more generous with their taste. If you like spinach you will love sea beet!!

How to identify Wild Spinach or Sea Beet?

The plant is easy to identify, there are not many plants like it on the UK coastline. The plants thick and succulent leaves make it look like very little else on the shoreline. Its leaves are brilliant green and the newest leaves triangular to spoon shaped with a thick stem running up the middle of the leaf. As the leaves get bigger (up to 40cm) they begin to look more distorted or crooked, deepening in colour and becoming a much darker green.. The leaves are available all year although in some areas although their official season is April to October with the young leaves being best in April and May. The plant sends up a flowering stem between July and September that can be laden with very small green flowers.

The whole plant is edible including the flower spikes - considered by some to be the best part of the plant. It can be found and harvested all year around, but in the deepest Winter months it is best left, wait for new leaves in early Spring. The roots which are bulbous have a mild beetroot flavour - One little warning about the root though, you are not allowed to remove the roots of plants without the landowners permission, as most of the seashore is owned you will have to find out who owns it prior to digging up anything. Why not leave the roots though and just pick the delicious young leaves or try growing your own!

Growing and propogating Sea Beet

Sea beet prefers a sunny spot and well-drained soil with plenty of organic matter added to it. Collect the clusters of seeds from the plant in late summer and sow in spring, it can be a little fickle to germinate, but you'll only need a few plants to keep you in leaves all spring and summer long.

Sea Beet alla Romana


2 handfuls of sea beet leaves washed

2 cloves garlic finely chopped

Olive oil

2 tbsps raisins

Tbsp toasted pine nuts

Chill flakes

Sea Salt and Black Pepper

Simply blanche the leaves in salted water for a minute, remove and place on a clean tea towel to dry out a little.

In a frying pan, gently cook the garlic in a little olive oil and with a small pinch of salt. Add the chilli flakes and raisins when the garlic is nearly done. Then simply add the sea beet leaves back to the pan, toss and coat the leaves in the garlic and chilli oil, season then serve.
