Re: Hellebore seeds?


Actually, Glider, all  Hellebores require first a warm period and
then a cold period.  If the seed is fresh, it will germinate like
mustard and cress after the cold period.  If it isn't, it can take
years to get it to germinate, if at all.  But, the key thing is to
start them out in warmth, not cold.  I would not resort to freezing
them.  You can simply sow in fall, while weather is still warm, and
leave outside to take what the weather will give them, when they will
germinate in spring; but if you have them inside, you don't want to
take them from warmth to freezing.  'Spose if you really want to
freeze them, you could after having them in the fridge for a while. 
If seed is purchased and has been dry stored, alternating periods of
warmth and cold sometimes help.

Have to say that a lot of purchased seed will never germinate because
it has been dry stored too long.  Dry storage seems to set up strong
germination inhibitors in the seed.  H. foetidus seems to do well
after dry storage, but most of the x hybridus clones do not.  Learned
that one the hard way.  Kept my seed pots for something like 6 or 7 
years...seeds still hard and sound, but never germinated...did grow
magnificent crops of moss on those pots, tho'.  Now, I always top
pots with a half inch or so of grit, which discourages mosses.

I always soak my seeds for a day or so in lukewarm water to which
I've added a drop of dishwashing liquid, like Joy.  Rinse and sow. 
Soaking seems to help with the initial hydration of the seed if it's
at all dry.  Collected seed is best moist stored in warmth....ya'
gotta check it for mold periodically and wash the seeds if you find
mold and discard any rotten ones.
