The flower is the rapeseed, as in rapeseed oil.P.s for the canola oil guy no canola oil is not good for cats at all in their fur and their food in you by tablespoons they should not even be smelling it it's not good for humans and the flower that canola oil come from is not caught a canola I can't remember what it is but it is poisonous so don't give it to your cat.
I would like to know what you are thinking on?? I know some margarines arent that great, and margaines are often made from rapeseed oil.
But margarines are of course made on cheap rapeseed oil, ie warmpressed oil. Also, they use inferior palm oil - which they proceed heavily. Not even mentioning, this palm oil is often transported in tankers who transport also other fluids - not always cleaning the tanks good enough between the transports...
So nothing peculiar these margarines arent that healthy.
While we are talking about coldpressed - usually organic, oil of first rate quality. No fancy additions nor peculiar processing.
