A friend from my youth always had an encyclopedic knowledge of plants, could identify them effortlessly just as we were walking around. I always envied him, but despite a love of plants, gardening, et cetera, I never went beyond a surface level until I started casually following Joey and CPBBD during COVID times. A big theme of what I've learned from him is how deeply geology is intertwined with plant evolution. Seems obvious once you hear it, but I genuinely never considered it until then.

At some point he taught an online course called "Blue Collar Botany" that went through plant ecology, evolution, identification, and other topics. It was fantastic, and finally got me into learning about the plants around me more rigorously. Years later, I still hear his voice in my head when I see certain parts of a plant like a laminar stamen. His affect is so unique that it actually helped me remember the content easier.

I don't know if he still teaches it or sells the videos from those sessions, but I would recommend it to anyone who wants to learn more about the natural world around them.
