Buying from an actual grower rather than a retailer is probably a good idea. We had a funny incident here with box store roots.
The packages were offered in August and labelled as Coral Charm.
I had picked up one and then decided they were a good price and went back to get another one. The rack was empty! So I went to another of the same store…….rack is empty!
Fine I planted it, and it bloomed one flower the following spring.
However,it certainly was not Coral Charm…..but likely Kansas?
Then I see one of the small plant sellers advertising potted Coral Charm peonies. I think I know who bought up all those roots!
But the joke is on them once those flowered.
