Why do different flowers have different smells?

For the most part, flowers smell really great, right? They give off scents that are sweet, syrupy, perfumy and fresh. But they don’t all smell the same. We asked botanist Josh Felton from Colorado College why that is. Got a question you’d like to sniff out? Send it to us at BrainsOn.org/contact, and we’ll find a budding expert to give the answer.
