A perinnial wildflower that is common , both in Europe,
and the North America's and Australia. This flower is
very poisionous and a danger for cattle.
Normally, the cattle avoid eating
the Tansy ragwort, but if the herb is mixed with hay, it
may kill horses and cows. Sheep love to eat Ragwort and
can handle the poison, but not in large quantities.
the poison
The poison is very strong but has some qualities:
-Its only poisioneus after passing the guts, so it safe to touch.
-It become far more poisioneus after the skin has been in the sun.
-The poison won't become less poisioneus after drying or storing
for a long period.

This is the species that grows in the dunes and
has a stark resemblance with Tansy.
The cinnabar catarpillar is effective in eating large amounts of the
Ragwort, stripping the ragwort from its leaves. This catarpillar is
poisioneus itself , so birds won't eat them. Starvation is there
biggest problem. The catarpillar forms a peaceful moth called theCinnabar moth,

is a problem as Ragwort and St Johns
wort are both dangerous for cattle and humans.
