After living a life of stem for the last 7 weeks, we need a break! So this week, you get a bonus episode: what is a leaf? In this episode from 2021 we discuss what a leaf is, how they grow, and some defining characteristics. To coincide with this bonus episode, we are expanding our CONE CLUB to include our very first--you guessed it--LEAF! The Bur Oak leaf illustrated by Caylin Jayde. We hope you love it, and if you want to receive this illustration as a sticker next month and support the show, join the Cone Club over at arbortrarypod.supercast.com. See you next week!
