Quote - Those green spots look to me like the sepals showing through the
spaces between the petals.    Maybe try hiding the sepals, if they're
a separate group, and see if the background shows in those same spots?

Edit: in other words, it looks like an effect you might see in the real flower
if there aren't a lot of petals....

LOL...That was the first thing I tried. I made those transparent and I get the same thing.
