No problem! These galls are often crazy-looking like this one. Those flowers are also pretty awesome!

Oh wow, I would have never guessed that one. I had no idea such a thing existed. Thanks for the lesson! I assumed it to be a flower, since it looked similar to some of the flowers we had in Hawaii:

The plant is a rose of some sort (Rosa) but what you are looking at is a gall made by a wasp (probably Diplolepis rasae)
