Defender

Help! I am sure this is not ‘Defender’ although it came from a nursery  specializing in Saunders peonies and all other cultivars I received from that source have been correct.  Both the flower color and the filaments do not correspond to the description by Silvia Saunders.  A very pretty flower though so it would be nice to identify it. Any ideas on what it could be?
