Hi Jim,
Your
regular that you have saved for years have a great landscaping plant. I think it is admirable that you have saved seeds over the years to create what is essentially your very own strain of zinnias. I am beginning to do that as well. I have done a lot of cross pollinating, but sometimes I don't know what caused a particular effect.
That zinnia has a concentration of color toward the petal tips and also somewhat toward the edges of the petals. That is a kind of odd effect, and I have no idea what caused it. But I kind of like it, mainly because it is "different". It also has some white streaks on some of its petals -- also a mystery as to what caused that. You can see the streaks much better in the big picture that appears when you click on the picture. I probably will save seeds from it, to see if that characteristic appears in its progeny.
