Columbine: The Witch Flower

If I was a witch (a wicked one) and I had a garden, it would be filled with all kinds of columbine. For some reason this flower always makes me think about witches. Does that make me crazy? I mean look at those spiky petals. Don't you think they look kinda evil and spooky?

Can you think of any other spooky flowers? Or does anybody have a witch garden?
