Heliotropium europaeum L.
Family: Boraginaceae
Common name: European Heliotrope, European Turnsole, Common heliotrope, caterpillar weed or potato weed.

Heliotropium europeum is a very common summer weed of cretan flora. It is an annual weed native of southern and central Europe, western Asia and northern Africa.
Accidentally introduced to South Australia during the 19th century, it is now recorded in all states except the Northern Territory and Tasmania.

It is not suitable as food for live stocks due to high concentration to pyrrolizidine alkaloids, commonly referred to as PAs. It causes liver damage and reduced productivity. Horses, pigs, cattle, sheep and goats can all be affected, but display decreasing susceptibility with horses being the most susceptible.

On the other hand a) is a good source of food for honey bees and b) is rich in one of crystalline Retronecine acetone used in cancer therapy. This is a very popular method of treatment for this plant is called in Europe Herbe Du Cancer (cancer herb).

There are natural enemies which can control it efficiency e.g. the fungus Uromyces heliotropii Sred the flea beetle Longitarsus albineus Foundras and the microlepidoptera Ethmia sp.
