Dennis,
Perhaps we take it so much for granted that we even tend to overlook the
fact, but nearly all modern bearded irises are tetraploids, and the results
have been so spectacular that it can well be argued that no other
ornamental plant has so clearly demonstrated the potentialities of
tetraploidy. As a single example, true pink color in bearded irises is only
expressed in tetraploids, although the specific genes that produce it were
present in the diploid ancestors of pink tetraploid irises.
