Blue Anemone
 

For many Norwegians the Blue anemone is a sure sign of spring.

It grows in all its splendour while the ground is still covered with dead leaves. The buds are formed in autumn, so everything is ready to flower as soon as the snow starts to melt and the sun begins to heat the ground.

The Blue anemone can have several colours. White, red and light green, but its most common as blue.

It thrives best in deciduous forests without too much light, but can also be found in coniferous woods with calcareous soil and a favourable climate.

 

About 40 years ago it was not unusual to find Blue anemones in Vennesla. But because the factories discharge sulphur dioxide into the air, which leads to acid rain, the number of Blue anemones in the area have decreased considerably.  It was mostly those who grew in calcareous soil that survived.
 

In densely populated areas the Blue anemone was picked with the root, and therefore became extinct in these areas. The authorities feared that it would disappear, and consequently it was preserved.

Today people are more concerned with what kinds of substances are released into nature.

This has led to less acid rain and the Blue anemone has therefore started to appear again.

 

In Vennesla it can be found in great numbers at these locations:
  • Langevannet
  • Lolandsvannet
  • Naspetjønn
  • The target range in Vennesla
  • Behind Grovane chapel
  • Jordvann
  • Moseid by the log pile
