In my experience, they won't come up this time of year. The ones i've brought in have always quickly died to the ground. On the positive side, they make excellent spring house plants, coming up a month or two ahead of those out doors. You might pot them up and stick them in the basement, then next March expose them to light and watch them grow. A head start can make a big difference in the size of your plants by mid summer, since first year plants bloom much later than established ones, and are generally much smaller.

I would suggest sowing the bulbils in pots, either on the surface of the soil or just barely covered, then sticking the pots in a plastic bag in the fridge for 4-6 weeks. After you take them out and give them some warmth, they should pop up. Make sure to keep the soil moist at all times. They grow surprisingly well indoors (I have grown them under fluorescent lights, although from seed and not from bulbils).
