Nothing about it suggests that it is a hybrid.  I got the seeds from Parks
Seed years ago, so there is no way of knowing if there was the possibility
of hybridization.

It has bloomed every year for many years now.  Does that tell you

I doubt that I could bring myself to mess with success.  As long as my
plants remain happy and healthy, I'm disinclined to dig them up out of
curiosity about the answers to questions such as these. But, the
probability that a fertile seed germinated next to a plant is pretty close
to zero since I usually pull the seed heads when they are just beginning
to turn color and ripen them indoors (they never ripen before winter sets
in here).

I had another look at the plant that I think produced offsets (not the
gigantic one), and it sure seems like that the multiple blooms belong to
offsets-the three stems are all crowded together--doesn't seem that
seed-derived plants would come up so close to the mother plant.
Furthermore, judging by size, none of these are seedlings--all three
blossoms are of substantial size, i.e., nowhere near as small as the
blossoms on plants that are blooming for the first time.  All three have
set seeds.
