    I don’t know of any research on the petal number, but it is worth noting that 8 is the next Fibonacci number up from 5, so it may be a relatively minor mutation

    It’s in the rose family? I’d taken it (at first glance) for some sort of daisy!

    These are individual flowers, daisies produce a compound head of tiny flowers–each division of the disc in the center is a flower (floret) , as is each ray (“petal”). The family daisies belong to (now Asteraceae) used to be called Compositae because of these multi-floret flowerheads.
