I think Winter Sowing would work for Zone 7 and up, as bulbils when they naturally drop will sprout a little bit (note pointy end on some bulbils) and begin to pull themselves into the soil (protection)and grow some roots as winter cold sets in, much, to me, like acorns, and then send up top growth in the warmer end of spring. Zone 6 may already be too cold for them to settle in...I don't know...
Seeds should be fine for Winter Sowing as they don't really do anything until mid to late spring. The first year seedlings may be only small plants til following year... I like the bulbils because they are easier to pluck out as the bulbils stay attached!
@Vma4922 looks like you and nature have already winter sown your bulbils! Around
mid May look closely underneathe your plant for tiny little sprouts. You'll know them by their first tiny leaf just like the big ones with that shape and red veining. Some plants produce more bulbils than others and it fluctuates by years, too.
