Will White Garden Mums Stay White The Following Year?

Question

And will cuttings from a white mum grow white?

Answer 1

Yes, it should stay white. My white mum has returned for 20 years. There is such a thing as a "sport," which is a mutation that could result in a color change, but that is not the norm. A cutting from the plant should look identical to the parent plant.
