Did you know

  • Cape sorrel is one of the world's most invasive plants, having colonized every continent except Antarctica.
  • A single plant can produce up to 20 underground bulbils per year, making eradication nearly impossible.
  • The leaves contain oxalic acid and have a tart, lemony flavor; they were historically eaten in small quantities as a salad green.
  • Cape sorrel was accidentally introduced to the Mediterranean region in the 18th century, likely through contaminated soil in plant shipments.
  • The flowers close at night and on cloudy days, a behavior called nyctinasty, controlled by changes in light and temperature.
