Five petal dogwood flower.

I am back to a flower blip today. My neighbor has a wonderful dogwood tree and I noticed today that the flowers have 5 or 6 petals. I think dogwood flowers usually have four petals, right? 

I photographed a different dogwood and all the flowers only had petals....kind of think that proves my point....or maybe just some have a set amount of petals.

I think I think too much about trivial things? :-)))  I came back to edit this because I read that the petals are not really petals but bracts; the flower is actually the center of what looks like the flower. 

Thanks for all the stars and hearts yesterday.
