Hinkley, Explorers Garden, propagation notes: "Sow fresh seed soon after harvest, may take up to two years for all to germinate"

He means fresh seed outdoors or in a cold frame where the seeds will experience a range of temperatures while moist over several months. Knowing you will have these seed pots for some time, you'll want to top your pots with some grit (crushed granite, chick grit) to discourage moss, liverworts....the suggestion is that you keep the seedlings in pots for approx 3 years after germination before installing in your garden.

You might be able to speed up the germinaton process by giving the seeds more abbreviated periods - sown, warm for several weeks, then placing them in your refrigerator for several weeks, bringing them back out to warm. If you have lots of seed you could try some both ways.

RE: Sowing cardiocrinum

I also have some questions about cardiocrinum.
I got fresh seeds... but they were fresh in November.
I sowed some in a container outside (freezing temps) then another pot in cool conditions, rather cold but not freezing (this on my balcony, glass enclosed but not heated) and yet another one smaller container (like margarine) in the fridge.
I still have some seeds left and I am not sure what else to do - as far as sowing goes.
These seeds came from a gardener so for sure were fresh.

Tried some bought seeds last year and two years ago - germination ZERO.

I tried to get info online. I haven't managed to read or see pictures of successful Cardiocrinum seed germination.

Lots of info, but no proofs. WHY NOT?

Some say the seeds need to normally go through weather elements like freezing temps, some other sites say NO FREEZING. Who should I believe?

Is there someone on this forum with a successful story? And pictures of a tray full of seedling? I'd like to see one!

Page from a study including their photos here. Note the dates, sown fresh in Nov, germination beginning 17 months later....

Here is a link that might be useful: Cardiocrinum

Wow. Then there's a chance. Too bad they don't explain exactly WHERE the pots were placed for all those 17 months...
THANKS!

Since not mentioned as otherwise in propagation notes from Hinkley, you are safe in assuming in a cold frame or someplace protected from wildlife outdoors, that the seeds have been exposed to seasons (not greenhouse or artifically controlled temps) - a range of temperatures as they would be exposed to in their native setting.

If you are having trouble finding germinaton instructions for a seed, it can help to look at the country of origin, then copy that as best able. When does the seed ripen, what happens weatherwise next after it falls from the plant....

Thanks Morz8 for all advice.
Since the last batch was the fresh-est, I think I have better chances with it. Also, many seeds and more techniques.
But I will only know in spring 2013...
