The rest might still germinate, don't worry, keep watering them.
I had an absolute TON of those seeds germ.

I like to do the warm/cold/warm (or cool) for almost all iris, and Fall sow them.

My siberians self sow, definitely getting the warm moist preceding the chill.

I have 16 iris chrysographes seedlings poking up as of yesterday, not sure how many seeds I sowed though. The first seedling or two appeared weeks ago, germination has been really spread out. You should keep your container intact a while yet...

I've only sown Siberian iris once, but sowed them in June with no pretreatment and had really good germination.

I WS Siberian iris seed last year and had great germination. I planted the seedlings in various beds and this year a few have sent up flower buds. I traded for more seeds back in Dec-Jan and just in the past few days finally have sprouts from those WS seeds. Comparing last year's germination to this year, I'm guessing they need a bit of warmth to germinate--it's been consistently cold this spring as opposed to the abnormally high temps we had in April last year.

Thanks everyone. I will look at them tomorrow. :)

Grdenweed, it's very interesting to know that you got flower buds this year. I have some Siberian Irises that grew from transplants. They took a long time to actually get established ad bloom leading me to think they would take years to bloom from seed. I think I will save seeds this year: I have a new bed to fill.

I had some germinate (seeds from a swap). When I planted them out, something ate them. Bunny I think. So keep an eye on them!

Still waiting for mine :)

Congratulations! I had given up on mine. I'm going to check them. I would like to see seedling pictures?

I'm up to 22 seedlings this afternoon, 6 more have germinated. Ladyrose, I don't have a picture taken of mine but they look like the tiny tip of a very pointy, sharp, stiff blade of grass, no seed leaves.

Sure ladyrose, I'll post a picture tomorrow. I agree with morz8 about the description. :)
