anyone know what this is?

Ranunculus?

It looks like a Pasque Flower, but I've never seen it in red...it must be in the Ranunculaceae family somewhere!

I've just found a red variety - "Rode Klokke" syn. Rote Glocke

Thanks! I got a packet of pasque flowers in a trade as an extra, but the seeds were 'fulfuf' with a long tail like clematis seeds, but these seeds were just on a stem and I was able to rub them off, no fluff, nothing. Anyone know if what I got was pasque flower?

could it be some sort of cosmo?

I concur with the Pasque Flower, definately!!!
