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.
Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
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.

Fort Collins, CO zone 5b
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!
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.
Zone 5 Georgian Bay, Central Ontario, Canada
Campanula thyrsoides, 17 days after sowing. Room temp, unheated propagator, indirect light. Thanks Lori,
53.69° N, Dedicated to West Coast Fritillaria, plus three other members of the subgenus Liliorhiza. I grow other Genera, as time permits !
You're welcome! Glad they're doing well for you.

Anemone narcissiflora - stratified for 7 weeks; germinated in 5 days at room temperature.
Campanula betulifolia - stratified; germinating in the cold/dark at 7 1/2 weeks.
Balsamorhiza rosea - stratified for 6 weeks as per Alplains instructions; germination in 2 days at room temperature.
Campanula piperi - stratified (Alplains said 8 weeks); germination in cold/dark at 5 weeks.
Nardostachys jatamansi - stratified; germinated in cold/dark at 3 weeks.

Probably the coolest seedling I will grow this year, at 9 weeks old:
Erigeron compositus Mt. Adams Dwarf
Rick Rodich zone 4a. Annual precipitation ~24 inches
near Minneapolis, Minnesota, USA
Very pretty baby Rick
in Devon, UK Zone 9b
Cute thing, Rick. Does it sting?
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
It's actually quite soft.
Freshly harvested Corydalis seeds. Again, I missed most of them....
Corydalis solida and Corydalis nobilis
