At what point should I start worrying? I bought a number of seed crosses on the
Auction. The ones that I paid the most for have not yet germinated and they were received on March4 and planted the next day. All the others I've purchased are sprouting - except these very expensive ones. (sigh) Is a month or more usual?

Weather has been moderate. Warm days, but chilly mornings. No freezes. Outside on tables on deck.

I stratify my seeds for a month in my unheated basement at about 40 to 45 F after planting in pots of moist potting soil. After a month, I bring them upstairs and put them in a warm spot to germinate. Most seeds germinate within two weeks after being brought upstairs. So, they normally take about 5 to 6 weeks to germinate under those conditions, although some germinate around the three week mark, and the odd one germinates much later, but I would say the majority germinate about 5 weeks.

Here is a description of stratification:
STRATIFICATION: Stratification of seeds means chilling under moist, not wet, conditions to prompt the germination of dormant seeds. ... The suggested temperature range (see Griesbach) for daylily seed stratification is 0°C (32°F) to 10°C (50°F), with four to eight weeks duration being sufficient.

Do you think the outdoor conditions over the past month have been similar to stratification? If so, the above description says 4 to 8 weeks, although as I mentioned earlier, in my experience, most have germinated before 6 weeks.

Maybe our experts will jump in with some advice!

I used to have the same problem with seeds from the Lily auction until I followed Rich Howard's directions on using cold wet stratification. I haven't had any problems since.

Thank you Valerie for describing your process. I thought the seed sellers were giving their seeds some weeks of refrigeration before sending, so I hadn't considered further chilling, although I always stratify my homegrown seeds. I still have a week to go in your estimated timeframe so maybe all is not lost! I should be getting in the habit of adding additional stratification time just to be on the safe side. We've had chilly nights
down in the 30s. I've had good luck so far and have many seedlings in pots on my deck. Just not with these 6 seeds that I overbid on!!

Thanks to you too, Bob. I'll have to look up Rich Howard's instructive wisdom.

Perhaps it's possible that the seeds had been refrigerated but not stratified (not quite the same thing)? The stratification method Rich Howard uses is posted on his website:

http://www.ctdaylily.com/files...

A month does seem long for none of a cross to have germinated though. Without adequate stratification germination can be erratic but some usually germinate fairly quickly while the others in a batch can take weeks or months to get over seed dormancy.

I had some dry refrigerated non-cold stratification seeds take over two months to sprout in the greenhouse [Michigan cross] so don't give up yet!

I agree, if the seeds are still hard, just keep trying.

Thanks Sue, I guess I've been thinking that stratification and refrigeration were more closely related. I have enclosed seeds in damp paper towels in the past and refrigerated them - sometimes resulting in emerging roots, but since plants grow so easily here in California, I've sometimes skipped that step. If I lose these it will be a hard lesson!!

Thanks Pam and Dave.So much good information! Thanks for the link to Rich Howard, Sue..

Well I think sooby, is being a bit modest. Looks like that article was written by her and maybe Rich Howard uses that method.

Somewhere I got the idea that stratification was for two weeks - I had some seed on damp paper towels in plastic bags in the fridge for two weeks and then took them out and put on the counter (still in the bags with damp towels) - should I put them back in the fridge?

If the seeds you put in the fridge for two weeks don't sprout after a week, then you might want to put them back in.
Some seeds need no stratification. I have read three weeks mentioned as the minimum. So I try to give my seeds 4 weeks at least and five weeks if I am not in a rush.

Good News! I set my 3 pots on a warming pad (2 seeds in each) of the seeds in question, and whaddayano, I'm seeing green!! Coincidence, or did the little guys just not like the nighttime chill ? whatever...I'm ordering another pad or two.

Great news! Maybe they just needed an increase in temperature to make them think spring had arrived!

Some may wonder about my extra concern for these particular 6 seeds...It's because 1.) it looks like a fantastic cross (see pics) and 2.) I paid ten dollars and change for each seed!! However, Paul just commented, on another thread, that the pod parent in this cross - Pray Without Ceasing,- is now priced at $350 for 2 fans! Out of my league. (correction : 2 fans just sold on the Auction for $400.)
