Propagation: Surprise Red Coreopsis, 0 by jvw

Two years ago my mom gave me six coreopsis seedlings to start my new flower garden. I have no idea what cultivar they were. They are about 3 feet, yellow petals with red ring in the center. One of the seedlings turned out to be different though. It was mostly red petals with just a thin ring of yellow on the OUTSIDE.

As coreopsis do, these original plants were prolific reseeders. Well this year two of the plants came out with all dark red petals. There is just a bit of yellow striping on the underside of the petals.

I LOVE this "new" coreopsis. I'm going to save seeds but I'm guessing they will revert back to the original color.

Anyone experienced this with coreopsis? Any guess on my probablility of seeing it again??
Sorry for the poor quality of the pic

Thanks in advance
