Elongation Of Bloom Of Black-Eyed Susan

Q: I have something bizarre happening to my black-eyed Susan flowers. Do you have any idea what would cause the elongation of the bloom? 

A: I have always been fascinated by abnormal growth patterns on plants. In your case, the flower is fasciated. The phenomenon of abnormally flattened stems is called “fasciation.” Many plants are known to occasionally produce fasciated limbs. The fasciation results from bacteria in some cases and genetic abnormalities in others. It doesn’t physically harm your plant.
