    7 Deadly Stems: WRATH (Bullhorn Acacia)

    7 Deadly Stems: WRATH (Bullhorn Acacia)

    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?

Ms Porphyria ,

9.9 Golden Cones of Honour.

Adore this show. Two very likeable and amusing gents deep diving into trees. Each episode focuses on a particular species from anywhere in the world and covers everything from morphology to culture and sociology. Just fascinating ground this pair able to traverse with humour and intensity. Have especially loved the Australian tree episodes (Jarrah, Bull Banksia, Wollemi, Mountain Ash) But honestly, have loved all of them and proud to call myself a Fungal Associate. Keep up the great work guys.

Feeling the tree love

I really love these guys and their tree banter. Just discovered the podcast and have not stopped listening over my holidays. Well informed, funny and fascinating. And as a bonus I enjoy hearing them trying to pronounce Australian plant and place names. Strength to your arm fellas, keep up the good work promoting trees and their benefits.

Basically two guys talking about trees

This is my all time favorite podcast. It’s basically two (American) guys talking about a single tree species for an hour. But it’s clever, funny and full of cool facts about trees.
