Hi All, we brought a mum from a local store 2yrs ago, in a pot, it flowered then looked like it died, back in the spring the other half planted it in the garden, it has grown to over 6ft tall, and flowered yellow flowers about 4in across, it is a chrysamthemum, i have checked the leaves with others that we have , but I have never seen one grow so tall as this , any ideas as to what type it is? going to try and get a photo on here.. thanks ...
