Watercress is grown in a number of counties of the UK, most notably, Hertfordshire, Hampshire, Wiltshire and Dorset, although the first commercial cultivation was along the River Ebbsfleet in Kent. In recent years, watercress has become more widely available in the UK, at least in the South-East, being stocked pre-packed in some supermarkets, as well as fresh by the bunch at farmers' markets and greengrocers. Value-added produce such as the traditional watercress soup, as well as watercress pesto are increasingly easy to source.
