I planted some pink threaded coreopsis, another native perennial, on the west side of my house a couple years ago. It didn’t do very well last year, but this year it has taken off and actually spread, and now it is in full bloom! It was advertised as attractive to butterflies, but so far, all I have seen are numerous sweat bees, barely 3/8 inch long! These are the same bees I wrote about that have been pollinating our beans. In the first picture, I just wanted to show the coreopsis, but the second picture is greatly enlarged to show one of the tiny bees. I actually caught one at rest!
