Does anyone have this?? Someone gave me cuttings today and she was calling the plant 'mexican daisy', but I know it isn't that....looks to me more like something I had been told was Mexican Sunflower, but there are several plants that go by this common name. Does anyone have pictures? Her plants were many feet tall - over the eaves of her house and had pretty yellow blooms, maybe 4" across. She said it roots very fast and grows fast.
