Bachelor Buttons in Winter Condition

This is what bachelor buttons look like at the end of winter here in Tulsa.  I planted them from seed in 2001 and they reappear every season.  I collect and sow the seeds in the fall and keep some in the frig just in case something happens.  They stand about waist high and have light blue blooms.  The wood bees are especially found of them as are several other insects.
