Guessing Tithonia. https://en.wikipedia.org/wiki/Tithonia

Was there supposed to be a photo...?

I'm seeing these (Mexican Sunflower) clumps blooming furiously in St. Pete this week. I am envious. Mine, from a cutting, doesn't get enough sun, so every year it grows tall without blooming. Sure is tough - hardy. I wonder if more people don't plant it because most (all?) nurseries don't carry it (too awkward? not attractive until it blooms?)

These are some I cut down. I'd like to try and get seeds from these for next year. Would I get them the same way as from sunflowers? Thank you

So pretty! Seeds: http://www.gardenersnet.com/flower/tithonia.htm

But, this article doesn't mention that a piece of stalk stuck in a pot will re-start this plant (as it did for me).
