I planted a few Jack in the Pulpit seeds this spring, including three in a pot. They've all gone dormant, which I'm guessing is normal since they all did it at the same time. I dug up the bulbs in the pot just to have a look:

I understand it will take several years for them to bloom, but for the ones in the pot, I was wondering if I could speed things along by putting them in the fridge for an artificial winter, and maybe getting two growing cycles per year. If so, my two questions are:

1) How long would the artificial winter have to be at refrigerator temperature?

2) Would I have to give them supplemental light this fall/winter to grow them inside, so they perceive the daylength as longer?

I'm in zone 6, Lehigh Valley of Pennsylvania, which is where the seeds were gathered. This message is also posted at the Woodland forum.
