Friendship which is a very hardy, good growing peony:
NOID (most likely Krinkled White) - this starts a very light pink that quickly fades to white. Here you can perhaps see some pink accents. I do have some 1st year Krinkled White's planted and hope to lock down the identification this spring.
I will also say that first year Krinkled White blooms are, well, kind of ugly. They have a waxy translucence that isn't attractive and they are not very well formed. It benefits greatly from a second year where they fully develop a fragile paper-like appearance and start to put up a lot of blooms.
Same plant, year 1:
It is amazing the difference that a year makes.
