Deadly Poisons: Oleander

This week we are kicking things off by digging a little deeper into the King fern, aka my pick for Chaz Tennenbaum as a fern.

Remember last week when I said the Marattiaceae family was like the Royal Tennenbaums? Well, for the next few weeks I'm exploring that theory further by paring each family member with their frond-y counterpart.

This week we're taking a closer look at a giant grandpa that has captured the hearts, minds, and brains of tons paleobotanists- Psaronius, a now-extinct giant tree fern that's still teaching us a ton about what ancient ecosystems likely looked like. If you like oldies but goodies, fun fern facts, and doodles lovingly drawn by a researcher who REALLY wants to help you see what they are talking about, you'll love this one.

This week we are back with another deadly poison and true crime case, this time featuring an old favorite - Hemlock! If you like fun facts, folklore, or story heavy episodes, this one is for you! PS- sorry it is late! Between the technical difficulties and health issues it was starting to feel like this one might never see the light of day, but here we are! And we'll be back next week with an episode filled with plant secrets, botany drama, and a salacious scheme from rival businesses..I promise it will be worth the wait.

This week we're focusing on fungus, but continuing our deadly poisons series with Death Cap Mushrooms. These absolutely lethal little guys are killers in disguise, making them one of the most lethal poisons out there. Tune in to learn what makes them so dangerous and how they were used in a Beef Wellington that would send Gordon Ramsay to the grave.

For part 3 in the deadly poisons series we're taking a closer look at cyanide. Whether you realize it or not, you interact with cyanide a lot more than you probably think, and while this one is a bit less focused on a specific plant, we still cover a LOT of ground, including why plants develop poisonous compounds, cures, and cults.
