I have a mystery tree peony by Langeveld and the tag has faded into oblivion. All I can read is "No. 16" and I wondered if anyone can tell me what color/variety this one is...?

Langeveld appears to be out of business so the mystery is making me nuts. The tag looked like a faded yellow (I HOPE) so I bought on sheer luck of the draw. lol

Thanks in advance!
