The are up to 30 with a thick stem and central vein, and grow in loose, ruffly clusters from the sand or shingle. They might sometimes have a purplish tinge, particularly on the new shoots.

Seeds – the round seed pods each contain a single seed 

Uses

Food

Leaves – blanched or cooked like cabbage, they have a crisp texture and a pleasant nutty flavour a little like asparagus . There are records form the 17th and 18th centuries of the young shoots being forced and served as a delicacy, so much so that over-harvesting caused it to dissappear form some parts of Britain . The flowers are also edible, as are the seed pods for a short time before they rioen and become too hard. 

Medicine

none known – though it is very nutritious and contains ample vitamins, minerals and dietary fibre. 

Known hazards

None known.

Harvesting

Appears in early spring. It is in flower from Mar to May 

Potential lookalikes

It can resemble some kinds of cultivated kale, which are also edible. Sea Holly eryngium maritimum has similar coloured leaves and can grow in the same habitat, but their sharp spikes and thistly looking flowers should help you tell it apart.
