1. The mother plant produced just one flower. It dried, and produced 35 seeds. Now the second generation sunflowers seem to follow the footstep of the mother plant producing single flower. Except for 3 plants. They produced multiple heads. I guess the wild element of sunflowers is seeping through the generations.
2. Of the three, one exhibits a totally different multi heads. That single odd plant produces some kind of branches, not just heads....Even coming from a single mother plant, these plants are unique and very much individual in character. Even the wilderness gets in a controlled environment over a tamed and domesticated sunflower. Their DNA make-ups will continue for million of years....
