Of the world comes clear and fills with color.

They persist in the sunlit room: the wall paper

Frieze of cabbage-roses and cornflowers pales

Under their thin-lipped smiles

Their withering kingship.

How they prop each other up!

from The Thin People- Sylvia Plath

O my God, what am I/ That these late mouths should cry open/ In a forest of frost, in a dawn of cornflowers.

from Poppies in October- Sylvia Plath

This is one of the few true blue flowers for home gardeners. One of the others is Borage, which we offer in a lovely Art Pack. Cornflower is easy to grow and makes a long lasting cut flower. The color has inspired poetry, the name of a Crayola crayon, and has even been printed on collectible upstate New York-based Corningware goods. Also know as knapweed, blue-bottle, star thistle, and bachelor's button.
