Not all mutants are of the too-much-radiation, giant-reptile-takes-over-the-world variety. Artist Amy Davis Roth, of Mad Art Lab, photographed these black-eyed Susans growing in a California backyard. The flowers are exhibiting fasciation, or abnormal growth of the meristem of the plant. Fasciation can be caused by a mutation, a hormone imbalance, or environmental factors including viruses and bacteria, according to Tim Smith of the Missouri Department of Conservation.
