paeonia lactiflora 'Ewelina'

The origination and correct spelling of this peony is unclear, Dick Westland from Holland names it 'Evelina' and says it came from Poland, on a polish website (see below) Ulf Eliasson from Sweden found a similar peony named 'Ewelina' (which seems to me more accurate, if this is a polish breeding, named by a polish breeder, because this is the correct spelling of the name in Poland, and not 'Evelina'.)

breeder and breeding year?-Mikolaj Karpow-Lipski, 1977, Poland
