Well, although it's still very cold here, I had 7 containers with sprouts 10 days ago:
Sedum oregonense
Alyssum spinosum
Dianthus grationopolitanus
Centaurea moschata
Zauschneria garetti
Dianthus anatolicus
Lupinus NOID
But now it's freezing again during day and night. No higher temps expected until next week, so I'll have to wait and see if they survived the severe frost.
