A curse word ‘round these parts, the Arborvitae (Thuja occidentalis) is not a species in itself, but a cultivar of the great Northern white-cedar, a majestic and hearty tree of the North of America. This beauty can be found growing on the roughest terrain of the Niagara escarpment, so why do we plant it as a middling hedge and street tree in other parts of the country? Then, we undergo a massive rebrand of this stolen valor Tree of Life.

The dawn redwood (Metasequoia glyptostroboides) was once the water fir, a tree endemic to a small valley in China. But thanks to the likes of Chinese foresters, a Japanese paleobotanist, and American plant explorers, this tree is now a worldwide sensation. Join us as we journey to China, 3,000,000 BC and 1940s Japan to witness the birth of a forest giant.

It’s Completely Arbortrary’s Excellent Adventure! To begin this journey through tree-time and tree-space, we revisit the crown of the Pacific Northwest and the very first tree we covered on this podcast, the Douglas-fir (Pseudotsuga menziesii). A long-lived tree with indigenous significance, modern lumber hypersignificance, and a huge native range, the Douglas-fir has few downsides. Learn new facts about this arboreal everyman and its family on this bodacious episode of Completely Arbortrary’s Excellent Adventure!

Oh, Kentucky coffeetree (Gymnocladus dioicus), how we love you (please love us back). A tree living out of its time that makes every effort to thwart attention and interaction, the Kentucky coffeetree may be the most curmudgeonly tree ever discussed on Completely Arbortrary. Learn about indigenous dice games, ecological anachronism, poisonous parts and scarification—this truly is a tree that hurts to know and must be hurt to grow.

To conclude our miniseries on logging, we discuss sugi (Crytomeria japonica), a unique conifer that hails from the forests of Japan. In a nation spared by colonization, where tradition and modernity coexist, sugi and its growing and processing methods are emblematic of this non-dichotomous dynamic. Yakisugi (or burnt cedar) is a method of treating sugi wood by means of fire, creating a phoenix-like rise from the ashes, making the wood more impermeable, and more resistant to insects and decay. Then, we play Family Tree: Mario Edition!

What do you get when you treat trees like corn? A plantation, of course. And a whole lot of Monterey pine (Pinus radiata). A tree that grows stubby and wonky in its native range, the Monterey pine grows like a poster child for logging in New Zealand, where its stick-straight form makes it the tree of choice for an unthinkably large swath of logging land. But oh, that cone...

Welcome to Australia, land of strange plants. Jarrah (Eucalyptus marginata) is no exception! This superfluously hardwooded tree of the Darling Range of western Australia is home to many a marsupial, and sports an astronomically deep root system. But when it caught the attention of voracious European loggers for its striking wood, Jarrah's future turned irreversibly grim.

Logging has seen a stark evolution since its origins. What started as a wildly dangerous and often deadly process done largely by hand is now a multibillion dollar industry facilitated by manmade machines. Herein we meet our character, the eastern white pine (Pinus strobus), a ghost from the early days of American logging. In the first of a short series on logging, we hear the tragic tale of this quintessential pine species and the lumber barons who ensured its demise.

1000 years ago, Polynesians reached the islands of Hawaii. On their seaworthy canoes were only a handful of plant species, but among them was the divisively flavorful botanical wonderdrug known as noni (Morinda citrifolia). Known for its funky flavors and breadth of influence on traditional Hawaiian medicine, this pan-tropical tree knows how to grow just about anywhere a canoe can bring it. Learn all about noni and the much broader classification of 'fruit', this week on Completely Arbortrary.
