French Sorrel
French Sorrel is a flavourful, hardy perennial herb that has been cultivated for centuries as both a culinary and medicinal plant. Its tender, tangy leaves have a distinct lemony taste, making it an excellent addition to salads, soups, sauces, and fish dishes.
This low-maintenance plant thrives in a variety of soils, and its deep roots allow it to withstand drier conditions better than many other leafy greens. To ensure a steady supply of young, tender leaves, regularly cut back flower stalks before they mature.
