This is so weird. I had a hibiscus with a clear yellow flower. For Thanksgiving I picked one for a centerpiece with persimmons from our tree. The bright orange flower went perfect with the persimmons and some fall tree branches. I really didn't realize until I went back thru some pics on my phone that I picked that bright orange flower from a plant that was yellow flowered all summer. Every flower on it had turned orange. Is this a normal thing? I met a girl at a garage sale who said her's had done the same thing.
