Cut flower mystery.

[jackb]

We bought a package of Mixed Cut Flower seeds early this spring and we thought it might be fun to try to identify the flowers as they grew; this one has us stumped though. The plant is over three feet tall, long and slender, with lots of buds. I have included a closeup of the flower in the inset and wonder if anyone of the experts on this forum can identify this one.

Looks like Plains Coreopsis to me. A nice healthy plant!

Thanks, that is exactly what it is! I just knew someone here would know what it was.
