Celeriac

Celeriac belongs to the same species as stalk celery, yet it represents a different path of domestication. Its wild ancestor, Apium graveolens, is native to damp and often saline ground across Mediterranean Europe and parts of western Asia. Ancient peoples knew celery chiefly as an aromatic or medicinal plant, not as the large, mild vegetable familiar today.

European growers gradually selected celery for distinct traits. Some lines produced thick, crisp leaf stalks; others developed a swollen lower stem and upper root. The latter became celeriac, also called celery root. Its round, rugged edible portion is therefore not a simple root: it includes enlarged stem tissue where the plant meets the soil.

Celeriac became especially established in northern and central European cookery, where its ability to thrive in cool weather made it a useful autumn and winter crop. French, German, Belgian, Dutch, and eastern European kitchens use it in soups, stews, purées, gratins, and raw salads such as céleri rémoulade.

Today celeriac is grown throughout temperate Europe and on a smaller commercial scale in North America, including California. Its modern reputation is strongly European, but its deeper ancestry reaches back to wild celery populations around the Mediterranean and into western Asia.
