Pasque flowers grow wild in dry soils of Central and Northern Europe.
The juice of the purple sepals of the Pasque flower gives a green stain to paper and linen, but it is not permanent.
It was used to colour the Paschal eggs in some countries.
Eggs were boiled with pulsatilla flowers to dye them green for spring festivals.
The custom was later adopted by Christians for coloring Easter eggs and since the flowers appear traditionally during Easter time, it got it's English name Pasch or Pasque Flower.
Another popular English name for the plant is Shamefaced Maiden.
It was first used by Arabian physicians as a external application for ulcers, for the inflammation of eyes, toothache and headache.
It was introduced into homoeopathy in 1805.
The plant has a strong acrid taste.
It is eaten by both sheep and goats, but cows and horses do not touch it.
