Last year I found a tall (40 - 90 cm) plant with succulent leaves and a daisy like yellow flower growing on an inland island (Indian Arm) that was being developed. The plant has sticky leave and the flower buds which are star like. Any idea what it is?? If I was more savvy I would post a photo. I was able to transplant one in our yard and it is growing like crazy. Just would like to know what it is? Is it toxic? medicinal? edible? Invasive?
