Yep, Laura, I agree, it DOES look closer.

A cultivar with similar looking blooms. I’m not saying this is yours. Laura https://davesgarden.com/guides/pf/showimage/324359/

Hi byankle, I’m not familiar with “White Rock Larkspur’ species(D. leucophaeum). Googling yielded the image on the included below. I this the same one you had mention? To my eyes yours appear to have a fuller petals counts beside with those inner smaller greenish petals in the flower’s center. But, I’m not able to view these in person to tell more than its genus. Maybe you could ask the nursery about what varieties of Delphinium they are carrying and try to narrowing down from there. On the side note, we are glad you had come back with this very helpful photo. Now we don’t have to wonder anymore…. Thanks byankle. Best wishes! http://oregonconservationstrategy.org/strategy-species/white-rock-larkspur/

For Laura – it’s looking closer and closer to White Rock Larkspur. The leaves are forked just so.

I believe you nailed it Laura. What I thought were tails on the bloom turned out to be new flowers altogether. Thank you for sticking with it.

This make a difference with two flowers and the visible extra details. I think these two look like a cultivar in the Delphinium genus. The leaves make sense now. Check out the included link for Delphinium’s varieties. I think your mystery beauty finally has at least its genus. Also check out a cultivar called ‘Butterball’. Best wishes!
