Thanks, LariAnn. I knew this was a wierd plant, but that's pretty bizarre.
I'll try that for the babies I have sitting beside mama in the pot. I did a little poking around with my finger, and mama's got a pretty hefty tuber already! She just got 'dosed' with time-release fert for the summer, as we have a fert ordinance here forbidding application of any nitrogen fertilizer from June 1st to Sept 30th.
Don't think she made any seeds this year, but one flower is still standing . .. we'll see!
