Sorry, on my second posting I called it corriander. I meant oleander is dangerous to eat, but then i gogled oleander soup and behold , there is such a broth. But sorry, but not for me.
Oleander is a evergreen shrub with very pretty trumpet like flowers, grow to 4 to 5 foot high. Olive green, leaves similair shape to an olive leaf but 2 to 3 times longer.Never grown on a farm because if cows eat they are history. Classified as a toxic plant.Also not grown where inquisitive children may consume the leaf. If a child consumes any part of the oleanda it can lead to nuseas,vomiting,low blood pressure and even death.
