It sounds like a lot more research needs to be done to figure any of this out.

But what I'm struck by, Nell, is just how scientists don't really know the purpose of red foliage.

And it's astonishing given that, you know, red foliage is everywhere right now.

Well, it depends on where you are, right?

I love this tape.

I want to go back to the thing you said a moment ago, that there are some trees that can turn a bunch of colors at once.

They'll have like sections that will be or, you know, an ombre effect.

Like what is going on there?

Now, if this story inspires any more science in this area, please come back on Shore Wave next fall and let us know.

Shortwavers, if you find a perfect red leaf, please send it to us at shortwave at npr.org so we can admire your discovery.

Nell Greenfield-Boyce, thank you for coming on the show.

Thank you.

All right, short wavers, we have a quick favor to ask.

Wherever you're listening right now, leave us a rating or a review because it really helps listeners find our show.

I can tell you, we read everything that you all send in.

Like Morningstar0222, who called us an excellent podcast and said, of all the podcasts I listen to, this is the show I try not to miss a single episode of.

Informative, timely, and always contextual and presented by people that love learning and sharing that knowledge.

The only thing I like is there are times the short episode was not enough and I want links for more information.

That is a true short waiver right there.

Thank you so much.
