I had a lily in the house once. After a weekend away, as soon as I opened the door I thought something had died and was decomposing. It took me ages searching for a corpse to work out it was the lily. When I put it outside, it's scent was lovely, but indoors it was way too pungent.
Used to have a lovely flower in my garden but it smelt so strongly of dog poo! Pretty or not it had to go.
Well the common name for Dracunculus Vulgaris is the stink lily. It smells like a rotting corpse to attract the flies that polinate it.
