Any properly-given name for a plant, even if superseded, is still a properly-given name. There is no reason for plant hobbyists to change labels when plants are renamed. Professional botanists are expected to know the name history of their plants, but hobbyists don't need to know this. I would rather spend the time tending my existing plants, or planting new ones, than rewriting labels. I have been advised thus by several friends who are professional botanists. Leo -- Leo A.
