The link below may be of help. There are many ways to germinate hellebore seed, H. niger takes a little longer to emerge than H.x hybridus.

After looking over different germination methods, if you have questions on a specific way or if any of this needs explanation please ask.

Many in the forum have answered the question you ask, we should have a FAQ but do not.

Welcome to the hellebore forum Paul, I here ya knockin!

Here is a link that might be useful: Seed Germination

HELLO!!!
Yes, we are really here.
I guess my seeds from last year have germinated all right as I am finding little babies all over the place! I even cut off the flowers just before they dropped their seeds as Bruce sugested but I sure must have missed a lot of them. I have never seen a plant as vigorous about reproducing itself like these orientalis hellebores. If left to their own devices It looks like they would cover all of my property. Of course, they are very easy to pull up if I really wanted to get rid of all those babies.
