It seems to be impossible to unsubscribe to this group so I'll just ask a ? and see if anyone can advise me. I planted bearded iris bulbs last spring and they all put out leaves but no flowers. I'm wondering if it would help to dig them up as someone here in my area suggested- and keep them in the fridge for a couple of months. Do they need that cold period in order to set flowers? I hope someone is familiar with south Fla's zone 10a growing habits

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?
