…is also known as Giant Cow Parsley, Giant Cow Parsnip or hogsbane.
In Germany we call it Riesenschierling or Riesenbärenklau or Bärenkralle or Herkulesstaude.
It can grow to heights between 2 and 5m. The flowers are enormous. We found many of this plant along the river Kyll, I have never seen so many.
