An ancient, popular herb that used to be a regular ingredient in food since ancient times, and has enjoyed a revival. Sorrel saved many sailors from scurvy thanks to its high Vit C content. It is a slender, perennial herb with deep roots and long arrow-shaped leaves. The leaves and flowers have a characteristic tangy, sour taste. It is low maintenance and related to rhubarb. Occasionally sold in the UK under the names of Zuring (NL) or Oseille (FR).
