A favorite from Ted Kooser:

The Bluet

Of all the flowers, the bluet has
the sweetest name, two syllables
that form on the lips, then fall
with a tiny, raindrop splash
into a suddenly bluer morning.

I offer you mornings like that,
fragrant tiny blue blossoms–
each with four petals, each with a star
at its heart. I would give you whole fields
of wild perfume if only

you could be mine, if you were not–
like the foolish bluet (also called
Innocence) – always holding your face
to the fickle, careless, fly by kiss
of the Clouded Sulphur Butterfly.
