Question: I would like your comments on this abnormality, I've seen lots of these wildflowers but never anything like this.
Answer: This is common in most plants. It is called fasciation. It is most often caused by some kind of damage after the bloom buds are set such as a freeze.
Webster defines it thus: "a malformation of plant stems commonly manifested as enlargement and flattening as if several stems were fused".
