What was the “happiest place on Earth” before it was Disneyland? And what is it before that? We go back in time today to explore the dark history of the changes of this land from indigenous river people to farmland to massive theme park, and the one tree that survived it all, the Canary Island date palm (Phoenix canariensis).

Sweet Neem! That’s right, today we’re talking all things Curry Leaf Tree (Murraya koenigii), and all things curry! This Indian tree is one of the most important trees in India, and one of the most delicious. You may even learn a little something about “curry”. Then, we answer a question about kelp!

Bees go to trees and get pollen on their knees. That tree is very likely a Silver linden (Tilia tomentosa). On this episode, we talk about bees. Unlike the last episode in which we talked about bees, this one has a happy ending. Plus, learn about Honeydew honey (just don’t think about it too much before you eat it).

One of the world’s loneliest and most critically endangered trees, the Sahara cypress (Cupressus dupreziana) stands nearly alone in the dead center of the mindblowingly vast Sahara desert in northern Africa. With only a handful of these trees left, we ask the question… what in the world is going on with these curious reproducers.

When does a tree that seems to be able to provide so much good become a tree that is reviled for causing so much harm? Today’s subject is the beach sheoak (Casuarina equisetifolia) a tree that is loved and loathed by many, including the Loggerhead turtles (Caretta caretta) of Keewaydin Island, where some well-meaning locals caused harm to the local sea turtle population in an effort to stay the gulf winds.
