If it was a PV (preferential vernalization ) type it would rebloom
and perhaps continue for next year according to how well it was
growing. Then stop. If a fall cyclic that didn't have time, then once
and stop.

I am curious -- if I were to pot up a rebloomer and take it indoors for
the winter, would it rebloom because it stays warm year round?
