I concur. I don't know the details about George Sutton's iris, but
presuming this is not a case where every bloom has broken color, it may be
the result of one mutation near the growth tip when the plant is very
small. All growth on one side of the plant will have the mutated gene, all
growth on the other side will not. Hence, after the maiden bloom, you'd no
longer see two-colored flowers. There'd be (in this case) a yellow iris
propagated from increases on one side of the mother rhizome, and a "twin"
pink iris propagated from increases on the other side.
The classic example (I wish I could remember when it was introduced and by
whom) is "Good 'N' Plenty" - blue on one side, white on the other. They
were sold as two-rhizome sets. There was no expectation that either would
ever bloom with two-toned flowers again, but the two plants, together with
the story of their origin, made a nice conversation piece.
Happy irising, Tom.
