I found this Mezereon (Tysbast in Norwegian) in the wood yesterday.
It's a very beautiful flower, with a very nice scent. But it's also very toxic! If poisoned, victims experience a choking sensation. Handling the fresh twigs can cause rashes and eczema in sensitive individuals. Despite this, it is also commonly grown as an ornamental plant in gardens for its attractive flowers.
So look, but do not touch! :o)
