FS-PS, 18-30". These are only hardy to 30°
2024: I picked up 3 of these at Ace Hardware after they suffered some frost damage. They cut them way back and sold for half price. They look like they'll probably survive. I will pot them up, fertilize them, and see how they do in the greenhouse. None of the papyrus I planted from seed has shown up yet. I got a late start this year again.
2022: Put one in each barrel. These were really outstanding this year! Starting with 4" pots, they were a 2-3' high graceful focal point in all 3 barrels this year. I am attempting to overwinter in the pump-house, after cutting them way back so they'd fit on the shelf. We'll see; it's worth a try anyway.
