Is there a seed thread that I'm missing? I want to try growing iris graminea and iris setosa canadensis from seed next year. I plan to sow the seed as soon as I get them in moist soiless mix, bag them and then alternate 2 weeks warm and 2 weeks cold (in the seed fridge). Will that work? Thanks muchly.

Nope, nothing you're missing. I can't help, but I'm sure Dee will be along soon, if not I'll go get her.

I would take half the seed and do as you have stated and the other half I would put in a pot and sink in the ground and cover with pine boughs or anything to protect.

I agree with Dee how ever with the ones you are refrigerating I would leave them in the fridg 6 weeks moist not wet then start alternating.

What does alternating warm then cold do? Is this good for other types of plants?

Hi eclayne. Alot of perennial and bulbous seeds need stratification which are periods of chilling and warming to turn off the chemical inhibitors that prevent germination. This patterns what happens naturally to seed if it is outside in its native environment. There are lots of good germination guides on line that tell you which ones need it and the temperatures and the periods of time to use. I like this one. Of course it's always best if you ask someone who knows from experience which is why it's so great to have cubits Smiling http://tomclothier.hort.net/

Thanks dahlianut, I always thought about stratification as a straight plunge into the cold. Nice link. explains a lot.

Tom Clothier is a fountain of information and have used his information for years.

I want to try this with all my Fawn Lily seeds to speed them up and get better germination
