How do you moist pack?

You know those seeds that are supposed to have a short shelf life and are supposed to be moist-packed to keep their viability - How do you do it?

The ones which I have received, moist packed, have been in small plastic packets of moist vermiculite.

Thanks Caroline. I wonder what keeps them from getting moldy.

I wonder if treating the vermiculite with hydrogen peroxide first might prevent molds?
It is just an idea.
I am trying 3% hydrogen peroxide as a soil sterility for my blue poppy attempt this year. The soil swells and effervesces and then I seed it.

Sounds like a good idea to me. Hopefully someone with experience will let us know.

Yes, it would be nice if someone who actually did this would post a comment.
It may take time for them to notice this thread.

I am watching and waiting for an answer also.

Thanks for bumping, ants. Hope we get an answer.

The other thing that one could do is just turn around and plant those seeds---perhaps as a wintersow project?

Wow, Caroline, if I did that, I would have a whole forest of Magnolia trees & another whole forest of American Beautyberry! I have no room for all of them...

ants

amen.

Okay, not a great idea.
We will wait and see if someone with experience will reply.

When are the seeds dropped? If in summer you could direct seed, right in the ground, and let them sprout and grow there as seedlings. Transplant next year.

Thanks, Karen, but I was asking as it's easier to give away or trade seeds than seedlings, and I have very little room left in my garden to grow seedlings. For myself, if I want more of something, I often will direct seed right by the mother plant and hope for a few offspring. And a few of these short-viables will self-seed themselves like crazy, like hellebores and corydalis lutea. But corydalis is very fragile , and so probably not too easy to pot up and ship successfully. And my 2 tiny seedling beds are full up, and next year will be becoming regular beds when I plant the stuff I grow this winter. So that's my long answer.

I'm still here with you waiting for an answer :)

The answer you're looking for may or may not be at this site:

Of course I can't find it now, but I recently came across a discussion about placing certain perennial seeds in between damp paper towel layers and then bagging & freezing it (or leaving it outdoors to have Nature do its thing) as a means of safely storing until germanation. Or as a kind of winter sowing. Is that what you're looking for?

I suspect that in general any kind of moist storage that wouldn't result in mold or germantion would require chemical or temperature inhibitors/intervention. (Unless the plant was aquatic?) But maybe I'm not understanding the question~

Lots of excellent information at that site, at any rate! Germanation instructions for corydalis & hellebore are in the perennial database.

Thanks nedweenie. I couldn't find the info at that site. I am trying to find out exactly how to do "moist-packing" so that I can store certain seeds that I will be sending to other people, but not immediately, that require it for viability.
There's definitely a lot of good info at that site. I use it often for info on seed germination.
