Wow, you are really going to town, Sharon!  

Among the many very desirable things you're growing, it was interesting to see that Linum dolomiticum germinated at room temperature for you... I usually stratify flax, but I wonder if it's always really necessary?  What does "OT" stand for?

Did you end up having to type it all in, or were you able to copy and paste?

Quite a few lovelies there, Sharon!

 

And the Gentiana bhutanica didn't require any GA3?

Lori, I was surprised to find the Linum dolmiticum germinating so fast as it was intended to have OT or outside treatment. The seed pot experienced fluctuating temperatures in my greenhouse of 32C down to 1C last September in a period of 7 days. So I suppose the seeds got the alternating temperatures needed and germinated quickly. I estimated the germination was near 20C on the 12th day. BTW I did leave the pot of seedlings outside perchance they would survive the winter. Any germination results with -4C - +4C x weeks or OT are rescued pots from my unheated greenhouse for faster germination under lights.

The solution to copy and paste was using Google Chrome!  Next I'll learn how to edit.

Rick, no GA-3 used on Gentiana bhutanica!  But I just found Gentiana aff septemfida, a white hybrid, has germinated at 20C in 9 days after 4 hour GA-3 seed soak! They are now in a cold basement under lights to grow on cool.  As for Meconopsis aculeata, once it hits the summer humidity here out in the garden it may be short lived.

I would suspect that G. bhutanica may be one of the gentians that needs no pretreatment at all, given the very brief period of chilling before it started germinating.  For example, G. tibetica also sprouts at room temperaure without pretreatment.   

By the way, looks like the current name for G. bhutanica is G. vernayi, according to The Plant List.  An annual.  Can't find any photos of it:

Allium meteoricum - emerged in 20 days at 65F. One seed out of 15..

Allium sikkimense - emerged in 23 days at 65F.

Cerastium candidissimum - emerged in 7 days at 65F.

 

Erigeron compositus Mt. Adams Dwarf - emerged in 11 days at 65F. One month old. 2cm wide from tip to tip.

 

Scutellaria alpina - planted 9 April 2013-no sprouting so put in fridge 10 June 2013, and forgot about it.  Sprouted in fridge 15 Feb 2014.

Interesting that those alliums germinated without stratification.  

That particular batch of Scutellaria must take the record for the longest time to germinate!  A happy ending though.

Here's a seedling update:

Aconitum rotundifolium -  Holubec seeds from Kyrgyzstan (Chong Kemin, Kungei AT); seeds were stratified 6 weeks in the cold room and started germinating in the cold/dark.

Astragalus ceramicus v. filifolius - Alplains seeds from Colorado; germinated in 3 days at room temperature after scarification.  They are looking very "filifolius" indeed.

Silene chungtienensis - started germinating after 10 days at room temperature.

Artemisia filifolia - Alplains seed from Colorado; germinated in 21 days at room temperature.

Linum suffruticosum ssp. salsoloides 'Nanum' -  NARGS seedex; stratified, started germinating in the cold/dark at 26 days.

Andryala angardhii - Piatek seed; germinated in 15 days at room temperature.

Gypsophila cerastioides - germinated in 7 days at room temperature.

Convolvulus nitidus - germinated in 12 days at room temperature after scarifying; leaves are starting to get silvery.

Ornithogalum nanum - stratified; started germinating in the cold/dark at 9 weeks. 

Inula rhizocephala - seeds from Holubec (Kazakhstan, Ketmen); germinated in 23 days at room temperature.

Silene jenissensis - Alplains seed; germinated in 9 days at room temperature.

Xylorhiza venusta - Alplains seed from Utah; stratified for 4 weeks, then germinated after 4 days at room temperature.

Dracocephalum botryoides -  NARGS seedex; germinated in 6 days at room temperature.

>>>> Interesting that those alliums germinated without stratification.

I was planning on giving Allium meteoricum a cold treatment when one popped up.  But as I note, it was only one out of 15, which probably indicates an anomaly.

A few years ago I had germinated Alium sikkimense with only warm temperatures too.  Identification of the resulting blooming plants were verified by Mark.  While I didn't get as good germination percentage this time, almost every seed come up within 2.5 weeks in the first batch.

Also, from the same batch of Allium sacculiferum seed from Mark McD: 17 out of 20 seeds emerged within 3 weeks at 70F; when given a 40-70 regime, only one out of 20 seed came up.

 

And yes, the Scutellaria alpina was indeed a surprise!

It's really useful to be keeping those records, as you've noted.  I haven't started many alliums from seed and I tend to assume, from the few I have started, that stratification might be needed - obviously  not!

More bad, fuzzy seedling pics...

Campanula crenulata - Holubec seed from China (Haizi Shan, Sechuan); stratified for 4 weeks at which time they started sprouting in the cold/dark.

 

Arabis lemmonii - Alplains seed; stratified for 6 weeks, germination after 4 days at room temperature.

Arnica lessingii - NARGS seedex, collected Alaska, Gold Ridge, Juneau (thank you, Donor #51!);germinated at room temperature 

Erigeron humilis - germinated in 4 days at room temperature

Androsace fedtschenkoi - stratified for 7 weeks, then germinated strongly after 7 days at room temperature.  Given that this a biennial/annual similar to A. septentrionalis, I'm guessing now that it may not have needed stratification at all(?)

Incarvillea zhongdianensis - germinated after 15 days at room temperature.
