The commonly planted annual Everlasting Daisies you can buy in nurseries or in seed packets are cultivars of our Xerochrysum bracteatum. They come in every colour between pale cream and pink through to orange, red, and even purple, and of course white. They were developed in Germany from Australian material, and, I was told by the late Dave Mallinson, using genetic material from related South African species. Garden cultivars developed (i.e., selected) from chance mutations.
