Thanks Arlyn . I thought Joseph's Coat was a sport. Did NOT know Sherwin Wright is also a sport from the same iris! Honorabile must have had a lot of unstable genes.
So basically a sport is an increase that displays features that are not the same as the mother. With a sport all blooms on the stalk would be the same.
While, Chimera are random blooms on a stalk with normal blooms as well. Caused by stressors (weather, chemical, what have you). You would not find an entire increase blooming as chimera. Do I have that right?
