No.  They have always been in warm (65-70F to start).  It's hard to know for sure that the lowering to 60F did the trick, or if they were ready to sprout anyway.

I'd suspect they were likely about to sprout anyway... ?  I find it very hard to imagine that plants could reproduce by seed in nature if they really depended for germination on such minimal and timely temperature differences.  Seems like a strategy that would destine them to rapid extinction, but what do I know. 

Thank you for the info on Lilium lophophorum.  Only a couple of the seeds did not contain embryos so that's a start, anyway.

More germination today:

Echinops cf. nana -  germination after 6 days at room temperature

Aster limonifolium - germination after 6 days at room temperature

Aster alpinus ssp. dolomiticus - germination after 8 days at room temperature

Lotus mearnsii - germination in 6 days at room temperature after scarifying

Stanleya pinnata - germination after 6 days at room temperature

Codonopsis cf. alpina - germination after 8 days at room temperature

Ah, these easy ones are satisfying!  (Good thing too... Looking at all those lifeless pots/failed attempts at the end of the seed-starting season is always a bit of a downer.  ;-)   )

A couple more today:

Erigeron linearis - germination after 9 days at room temperature

Onobrychis montana - germination after 2 days at room temperature, following scarification.

Edit:  Here are seeds, as received on right, and with the prickly seed coats removed on left, prior to being scarified on the file shown in the photo:

And the resulting seedling... looks like I didn't scarify them too effectively, as I've only got one seedling so far:

 

The Onobrychis is this year's winner for fastest germination, so far!

Oxytropis campanulata - germination in 3 days at room temperature after scarifying

Edit to add photo:

 

Erigeron humilis - germination in 3 days at room temperature

Astragalus ceramicus v. filifolius -  germination in 9 days after scarifying

Silene jenissensis - germination in 9 days at room temperature.  (I bought a plant by this name some time ago... very invasive and I'm still pulling out the odd shoot.  I assume that this source from Alplains will be different - that is, a desirable plant for the rock garden and correctly-named, assuming that the invasive one was an imposter.)

Edit to add photo:

 

Plantago nivalis - germination in 9 days at room temperature

Convolvulus nitidus - germination in 8 days at room temperature after scarifying

Gentiana kyrilovii - germination in 6 days at room temperature after overnight soak in GA-3 solution

Wonderful, and incredibly useful information Lori, across numerous Genera. I really must follow your lead and start to record more information. blush. I do it religiously for my Fritillaria, but the other Genera I don't. You've made me realise that I'm just discarding very useful, easily recorded information. [ must try harder!]

Seems like a posting issue occurred, as the  pictures for Androsace spinulifera and Campanula crenulata are the same. 

53.69° N, Dedicated to West Coast Fritillaria, plus three other members of the subgenus Liliorhiza. I grow other Genera, as time permits !

Thanks, Ron.  I do try to keep records, for my own interest, and in case it's useful to anyone else.  Funny, with all the time I spend on it, I still wind up with a few mysteries every year.  Seems the gremlins always delete a line or two out of my spreadsheet somewhere along the way!

Oops, yes, thanks for the sharp eye -  I've corrected the photos now, and gone back and added a couple to the older posting.

This is why I make a plea every year, both here and the SRGC: for complete (or at least useful) records.  Pictures are fantastic, but they don't tell the story of germination.

I've been recording usable information for a few years now (mostly from NARGS and SRGC forum) and adding it to a data base of Dr. Deno's work.  So far, I have over 550 added entries in the "Other Sources" column.  Lori is by far the most prolific contributor. (She is footnote #3.)  Thanks, Lori!!!
