So my favorite all time perennial is the beautiful Red Hot Poker plant... from the first time i saw this plant I am always looking to add more to my yard and learn more about it.

It seems as if there are two varieties that i have come upon that i have in my yard -- one is a spring/early summer bloomer and the other is a later summer bloomer.
I love the latter so much more.. that thing just blooms and blooms all summer but i have yet to find any more of these at nurseries in my area. I would like to try to grow some more
of these from seed... can anyone please provide some direction on how i can do this with this plant? It is rather large at this time so i could possibly split it ( that is possible, right?)
but i really rather not.

Any insight on the seedlings, etc would be much appreciated.

Thank you - Aaron
