Whenever I try to render my scene part of the object remains very grainy and the texture doesn't seem to render all the way. Only parts of the petals seem to render correctly for some petals, but other petals with the same material render fine. What is causing this?
I thought perhaps this was just fireflies or something to do with my lighting, but my teacher and I have tried multiple things and none of them have worked.
Your problem is that several of your petals are duplicated exactly on top of themselves. Since the petals are super high poly the z-fighting is not quite as obvious as usual.
This probably happened because you pressed Shift(or Alt)+D and then exited the operator with a right click (or by pressing Esc). This does not cancel the entire duplication operation, it just cancels the translation and drops the duplicate directly on top of the old one.
To fix this just select and delete all the unintentional duplicates. I would do this by selecting each problematic petal and checking if it has a material assigned to it, if not delete it; if so right click it again to select its duplicate, then delete it.
