Persicaria virginiana 'Painter's Palette' is a variegated-leaf cultivar of Persicaria virginiana. Wild type P. virginiana doesn't have variegated leaves, but its leaves do have the red chevons (one note, many species of Polygonun/Persicaria have those markings on their leaves).
I don't know which species of Polygonum/Persicaria you have, but do know that it's not Persicaria capitata or Persicaria maculosa, for whatever that is worth.
