    Are you sensitive? Do you show aggression when you're afraid or perceiving some sort of attack? Do you have a mercenary army of ants at your disposal to dispact at the first sign of aggression against you? Then you might just be a bullhorn acacia (Vachellia cornigera).

    7 Deadly Stems: GLUTTONY (Common Fig)

    7 Deadly Stems: GLUTTONY (Common Fig)

    The common fig (Ficus carica): one of humanity’s first food obsessions. From covering Adam’s junk to covering other Eve’s junk, this plant has no shortage of cultural import. But does it deserve the valor it’s flaunted for hundreds of years?

Love this podcast!

Hearing this content is a great feeling for me. The earth needs us to become educated and supportive of how to keep trees alive!!!! This planet needs trees-not religion or money. We need people who can help create the future as a better place. Thank you. Plus- you are super sexy smart. 😜🌲

Lovely Nature Themed Podcast: Humorous and Informative!

Hi Casey and Alex! I stumbled onto this podcast by way of Alie Ward’s Ologies and I’m working my way through the back catalogue. I consider myself a science and nature enthusiast and with each episode so far, I come away with increased biological and historical tree knowledge while being throughly entertained. This podcast does a fantastic job towards deepening our appreciation for the natural world around us. My fig tree 🌳 and I are big fans! 😁💜

Shake head

I’d love the show if they didn’t constantly try to find a way to put down Christianity.
