What subject should I write my Botany research paper on?

I have this one last pesky graduation requirement before I get my Bachelor's degree; a Botany course. It's a freshmen-level course in which I have to write a five-page research paper on something related to plants and their preservation or their use in our lives (i.e. medicinally). But I have no idea what to write on. I don't really have an interest in Botany so I would want to write on something somewhat interesting, otherwise this project will get really boring. So, any suggestions?
