How do you see the world? How do you organize the world, all the plants and animals around you? This week we have a discussion about taxonomy that revolves around the gorgeous Italian cypress (Cupressus sempervirens), and it opens a door to an entirely new way to see the world.

The Rocky Mountain juniper (Juniperus scopulorum), like nearly all junipers, is a conifer that took a different strategy to get its seeds dispersed. This week we chat about convergent evolution, and how nature can find the same solutions to problems in very different ways.

What does it take to be a perfect tree? We'll come to figuring it out this week as we dive into a flowing conversation about the giant sequoia (Sequoiadendron giganteum). Stick around for a discussion that explores everything about these trees, and then looks into where the term tree even comes from.

The hickories (Carya) are a part of an ancient forest system that once existed across the entire northern hemisphere, from North America to Europe, across Asia to the Pacific and back again to the North America. This week, we chat about the shagbark hickory (Carya ovata) and discuss how it and it's closest relatives have been so successful, yet ended up so far from kin across the world.

What do you do when the way of life that you evolved over millions of years was rendered useless in the blink of an eye? Something very similar to that happened to the Osage-orange (Maclura pomifera) at the end of the Pleistocene epoch, and it wasn't alone.

Has the European beech (Fagus sylvatica) been man's best friend since time-immemorial, or has it just been doing it best to impress the whole time? This week we discuss the complex history of the European beech, but the jury is still out if it's a natural history or unnatural.
