Evan,
Not a rumor - i had TWO blooms on my Typhonodorum and one of them seemed to be setting seed, then aborted on me. So I don't have any little ones - yet. The plant has slowed for winter but since it is so large now, this summer should be a good one for potential seeds. Believe it or not, I have a cross in mind, too, if I can get the other potential parent in blooming size for my work.
