After reading this link am I correct in my understanding that astrantia seeds do not need any covering or heat to propagate?  I have also tried to grow verbena bon., with no success, so trying again.  As v. bon. needs cold to break dormancy I assume they too will be treated the same as astrantia.

Mary - I found Verb. bon very easy from seed, but I did them in late spring/early summer.  

Meant to say - as nut said , astrantias (like Verb. bons)  will seed by themselves too, but they'll  simply sit through winter and germinate when ready. They don't need extra warmth.

Thanks Fairygirl.,........I tried both during the Spring and I didn't get a single seedling, very unusual, but I did have them covered.  Trying this time of the year without cover...........hopefully will get seedlings in the Spring.

I set astrantia in autumn, outside. I generally bring the overwintering seed pots into the cold GH around February. this might be more for my benefit than theirs. I also bring things in when they germinate, no heat, just shelter from the worst of the wet and pecking birds.

verbena about February in the cold GH

I use gritty compost and some more grit on top of the seeds, it stops them getting washed out or growing mould/algae/other undesirables
