Some more updates and some new ones:

Matthiola trojana - germinated in 12 days at room temperature

Oxytropis campanulata - germinated in 3 days at room temperature after scarifying.

Ononis rotundifolia update: 

A burgeoning potful of Helichrysum basalticum - germinated in 30 days at room temperature; a Sani Pass native that is successfully grown at the Denver Botanical Garden, so worth a try here.

Soroseris rosularis - seed from Holubec (collected: China - Xinduqiao, Sechuan); stratified for 4 weeks and started germinating in the cold/dark.

Convolvulus tragacanthoides - update; I ended up with one of these; if I could do it over again, I'd scarify the seed, which worked very well for Convolvulus nitidus (following the advice from Stephanie F.).

Dianthus myrtinervius - stratified for 4 weeks; started germinating after 3 days at room temperature

Androsace spinulifera - stratified, started sprouting in the cold/dark after 4 weeks.

Michauxia campanuloides - germinated at room temperature.

Erigeron linearis update:

Plantago nivalis - I'm looking forward to having these furry things in the garden!

Hyoscyamus pusillis - ditto!  Hope this one stays fairly small.

My first garden meant for Fort Collins, CO, my new home. Propagation began a few months ago. All sorts of stuff; seed and cuttings

 

Sedums, semps, and a bunch of alpines that needed no strat.

Recently I found the following had amazingly germinated at cold temperatures. The warmest temperature was probably 10C due to a heater running during the day reaching pots on higher shelves. Most of these were on the floor and germinated with alternating 0 - 4C temps!


Alstroemeria ligtu hybrid cold x 10 wks started to germinate @ 4C  
               
Asclepias cordifolia wild seed 8 wks cold started to germinate in cold  
               
Aubrieta  gracilis 4 wks @ 4-10C; germinated in cold    
               
Campanula aff pulla 6 wks cold germinated in cold @ 4C    
               
Campanula incurva 6wks cold germinated in cold @ 4C    
               
Draba bryoides in cold x 6 wks  germinated started at 4C    
               
Edraianthus serbicus 5 wks cold germinated at 4 -10C    
               
Linaria alpina mix 5 wks cold germinated at 4 - 10C      
               
Penstemon barrettiae OT in GH Nov, Dec; to 4C on January 2; Germination @ 4-10C in 4 wks.
               
Phlox colubrina 8 wks cold germinated well @4C.       
               
Primula beesiana given OT x 5 wks brought to 4C germinated in 3 wks  
               
Pulsatilla alpina ssp apiifolia after 8 wks cold started to germinate in cold
               
Pulsatilla halleri ssp grandis after 8wks cold started to germinated in cold
               
               

Interestingly also, is that I can't bring the germinated pots to temperatures of 20-25C!  They show signs of heat distress. So back they go to a cold room.
