Pulsatilla species

Here is another 'out of focus' photo.  :-[
I found the marker and plant which was grown from seed in 2009 labelled Pulsatilla alpina ssp. apiifolia. It is now in it's post flowering stage with up facing seed heads forming. Interestingly, I found a great discussion on the Forum in Feb. 2011 which leads me to think the seed was mislabelled.  It seems to be P. albana var. lutea. What do you think, Lori?
I'll have to watch it like a hawk next year for a proper id.

Hi, Sharon!  Please forgive me for not responding before now - I was hoping someone more knowledgeable would answer your question...  but, oh well, no response so ya got me, I'm afraid!  ;D ;D

Here are photos of what I had that was said to be P. albana var. lutea (gone now, unfortunately - seemed to have rotted out in a wet spring in regular soil, dang!) - it seemed to have more feathery foliage than your plant:
   

That really makes me wonder what yours is?  I thought maybe P. vernalis, but the foliage, while more "leafy" than feathery, doesn't really seem to match that either.  May I suggest posting it at the SRGC forum, since there have been no suggestions here?  I'm quite sure you will get an answer there (and please let us know when you do!)
Here's the link to the plant ID site at SRGC:

Could it be a unusual colour form of patens? The leaf looks very like seedlings we have of this and I think Trond showed a stunning yellow form (flavescens??) on SRGC. Whatever this is a particularly lovely plant - very distinct.

I dunno... P. patens typically blooms before putting out leaves.

I think the leaves look a little similar to vernalis.  But Middleton's plant has a different shape. Can it be a hybrid?

Here are P vernalis and flavescens for comparison.

Trond I love that color of the pulsatilla flavescens. Do you grow them.

I must admit from Tronds first photo the mystery plant does look like vernalis. I've always thought this was a sort of ethereal blue on the reverse, rather than the pinkish flush here. Pulsatilla flavescens is a complete beauty! I shall scour the seedlists every year for that now.

Sorry, no. I forgot to mention it is from the Botanical Garden in Oslo.

P vernalis grows at our cabin in the mountains. Although it is native in Norway and common many places it was completely extinct in that area due to collection. I have planted several the last years but this year all buds were destroyed by frost and hares :'(

Hopefully next spring there will be more flowers and I can watch it more closely for a proper id.  That yellowish hue on the inner petals is propably just the first flush but turns white as in the P. vernalis. It is a beauty as is the P. flavescens!
Thanks all for your input.
Sharon

The whole plant, P. vernalis.
