Flowers in the hayfield

This morning when moving irrigation pipes I saw two bright blue flowers growing in the hayfield.

I don't know what kind of flowers they are but they are pretty.  The photos don't do the flowers justice.

I have covered the hayfield once and now am on the way back moving pipes.  The grass and alfalfa are sure liking the water.  The weather here now is hot (about 90 degrees), sunny and dry.
