The easiest way to grow hellebores from seed is to do nothing!
By that i mean just let your plants get on with it themselves.
I have 2 plants growing in a raised bed with an area of gravel just next to the bed. One year i let the plants seed and sure enough the following spring up popped masses of little hellebore seedlings in the gravel. I think i ended up with enough to start a hellebore nursery had i wanted to!!
Of course there is no guarantee of colour with self sown and of course you are stuck with the same set of genes as the parent plant. So no good if you want to diversify or start a hellebore collection.
I guess with sowing seed yourself (ie with saved or bought seed) you have to be prepared to be patient. Even my fresh self sown seeds took a long time took nearly a year to germinate, though i suspect they would still have come up in spring if sown the previous autumn, requiring the cold of winter to stratify them, rather than a long period of time.
It might be worth sowing around now in a pot of gritty compost and leaving outside in a sheltered but not warm position and seeing what comes up in spring. I know you can try to cheat nature by using the fridge but i have never found this to be as reliable a method as letting nature take its course.
