I would like my poppies to bloom a little later, so they coincide with my delphinium. If I cut back the first flower sprouts, will they produce new ones? Analagous to cutting the central stalk of a dahlia.

I dont think I have ever heard of this but the question intreagued me so here is a You-Tube that suggests you can cut back bloom stems and the plant makes more.
I hope I understood her correctly.

Re Papaver orientale; not to my knowledge, at least here.

By mid to late summer the whole plant goes dormant.
The problem with this is that if several are planted together, in a mixed perennial bed, you'll end up with a big gap for the rest of the growing season.
(I cut the dead plant material down as quite unattractive).

Below a cultivar I planted in 2008 and which was still going strong this year.

I'd be wary of cutting them down in hopes of delaying/extending bloom. I watched the YouTube vid and I am not sure I trust the information....mostly because Papaver orientalis (the perennial poppy) is absolutely NOT the opium poppy (P. sominferous...not sure of spelling; this is an annual poppy). If the presenter is not sure of that fact, I don't think I'd trust her information. I'm always leery of those who don't get important facts right.
The end is nothing, the journey is all.

Even the so called Super Poppies that is said to be a rebloomer is questionable at least in my Z:5 garden.
