Thank you for sending us your gardening question. It sounds as if the plant you have has experienced some mutation. A mutation is an accidental change in an organism's heredity genetics. Mutations occur in plants as well as animals. Mutations have many causes ranging from chemical and radiation stress to environmental trauma and man induced changes. Some mutations are beneficial to the survival of an organism. Some are not.
