Cow parsley leaves

Cow parsley leaves are green and feathery, almost fern-like in appearance but often inconspicuous as the plant pushes its flowers up through the lush spring growth to the prime, sunniest air.

The stalk is striated, the vertical ridges becoming more distinct as the plant withers and dries.

Cow parsley vs hemlock

Any would-be foragers pondering the culinary value of umbellifers need not look beyond hemlock as a potentially deadly example of misidentification. At first glance cow parsley and hemlock may appear similar, but while cow parsley is edible, hemlock is poisonous and, when ingested, can be fatal to humans.

Is cow parsley dangerous?

Cow parsley is edible, but it can be very difficult to identify from its very poisonous relations, such as hemlock and giant hogweed so should only be touched if you're 100% sure of your identification.

Another name for cow parsley

Another similarity to hawthorn is within the shared alternate name, ‘mother die’, the meaning of which was perhaps a deterrent to prevent its picking by uncertain hands. For although cow parsley is edible, and its young leaves sometimes foraged for salads or omelettes, it can be difficult to identify from some very poisonous relations.

Another old name given to cow parsley was ‘Queen Anne’s lace’, so given because when the Queen toured the country following her coronation in late April, the lanes were decorated white as though in her honour. Anne struggled with her health, and it is said that she would walk in the countryside to ease her breathing, while her ladies in waiting made lace in her wake.


There is certainly a lace-like quality to the flowers, and the name itself seems far more fitting than the common name which points to its apparent culinary worth.
