Nope, never! Maybe the plant dried up for a small amount of time while they were small? Not sure…

I have seen some odd shapes over the years. I have no idea what causes them though. It will still be tasty!

Looks like a case of fasciation!

Fasciation has many causes both internal and external. Internally, it happens because of a hormonal imbalance in the growth cells, a bacterial or viral infection, or a random genetic mutation. There are also environmental causes, like chemical exposure, cold and frost exposure, or fungi, mite, and insect attacks.
