I leave all the foilage to die down on mine aym, home for some insects in the Winter. I think they probably are seeds but I'd say more likely to spread from the courns at their roots. I've got the plain old orangey one and it will spread if left unchecked.
Most of mine are now in pots, I've got a clump that needs coming out of the hot bed. I expect to be removing bits of it for a while. The Lucifer type always looks good, no space here for one
