Did you know

  • Alpine Penny-Cress is a hyperaccumulator that can absorb extraordinary amounts of zinc, cadmium, and nickel from soil into its tissues.
  • Scientists are studying it for phytoremediation, using it to clean up heavy-metal-contaminated soils at former mining sites.
  • A single plant can accumulate zinc concentrations up to 30,000 parts per million in its leaves without suffering damage.
  • The flat, round seed pods resemble tiny coins (pennies), giving the plant its common name.
  • It naturally colonizes metalliferous soils near old mines in Europe, growing where virtually no other plants can survive.
