If the "spot" below the log is indeed the "flower" of which you speak, it is most likely either a "grease" spot or a very minor strike through, both of which were very common on the date/series.
Books is correct, a minor struck through grease. See these all the time cent hunting. Some can be quite noticeable though. I have a few that encompass the entire head.
Technically, no, just some sloppy work at the Mint. If it had been struck through something major like a steel wire bristle or a piece of thread from clothing it would carry a premium. If it were bigger and bolder it might have some minor added value as an oddity. As far as it looking like a flower, if you look at something long enough, with enough magnification, it can pretty much be anything your eyes tell you to see. I think one of the most famous "eye wonders" of all was someone seeing the image of Christ on a potato chip. And it's probably framed in a shadow box and hanging in someone's living room.
In the most technical sense I suppose it could be considered one due to the fact this isn't how the mint intended the coin to be, but calling it an error is an unreasonable stretch imo. Like I said this sort of thing was painfully common for the date and series. One man's pareidolia does not automatically add interest or additional value for another; Jesus on toast has, of course, proven to be the exception.
