Ms. Bee Haven (Silver Linden)
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).

The Loneliest Tree (Sahara Cypress)
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.
