A pretty flower with an ugly name.

The dog's tooth violets are in flower, it must be spring.

Erythronium dens-canis is a bulbous herbaceous perennial flowering plant. It is native to Europe, where it is the only naturally occurring species of Erythronium. Despite its common name, it is a member of the lily family and not closely related to the true violets. It is very pretty though! Especially when seen through the gardener's looking glass.
