This reminds me of Margo Koster.

Thanks vaporvac!

I looked around & it could also be Mandarin ice.

Sadly, no one sells it in the US.

I see that now. I wasn't sure if it was just the reflection of the light, although on HMF it looks almost White on the back of the petals. The blooms also looked very globular, but I'm only viewing this on my phone so it's hard to get a good picture. I guess Chamblee no longer carries it? Have you spoken to them?

I thought of Mandarin Ice too. I’d go ahead and ask Chamblees if they still have it, it was on clearance last fall. I think Burling has Margo Koster

Chamblees does have it! Thank you both!
