Smyrnium olustratum - a medditeranean wild plant said to have been brought by the Romans as a herb, as it is related to things like Angelica and Sweet Cicely. It has the typical umbel flower and deeply-cut leaf, but is a more stout and stocky plant than many in this family, growing to about 3 feet (1metre). It is very early flowering for this family (April) and has the habit of only growing close to the sea coast in North Wales - but may well take to other gardens or containers.
In cooking it can be used as early spring greens with a delicate flavour.
