I only bought mine last year. The first year it was great, but I don't know what to expect. What's the best way to propogate...seed, bulblet, does it matter? Where do babies come from every year, do you do anything? I'm in zone 6, so I don't know if the mother plant will come back or I need to wait for the seeds/bulblets to sprout from what fell onto the ground last year. I also collected the bulblets, hoping to hedge my bets!
