The European to Russian Allium ericetorum, and Turkish scabriscapum & wendelboanum, are also easy germinators.  They could be sown now, placed outside, and can be expected to germinate as cool & moist spring weather arrives. 

Then would you say they would germinate better at 50 or 60F, as opposed to 70F?

Lori- did the Rhodiola need scarification? Atypical for Crassulaceae..

No, sorry, I didn't scarify the Rhodiola seeds.  That was another error from my too hasty cut-and-paste.

I sowed two batches of Dodecatheon pulchellum from two different sources on 2/2/13, and kept them at 60-65F.  Neither has germinated.  I've put them outside for cold treatment.  I have never seen this species germinate at warm temps.

Good to hear those Taraxacum germinated! I was worried maybe the seed needed to be absolutely fresh.
Just a note, for me, they have not wanted full sun (at least not while potted, just got some in the ground in fall) and don't seem to like to be dry at all....
