What does it mean to be “extinct in the wild”? Just ask the Franklinia (Franklinia alatamaha), who lives it existence only in arboretums and gardens. But it wasn’t always like this….

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). To hear Casey’s “Save The Bees” rant, join the Patreon! Completely Arbortrary is p...

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. Completely Arbortrary is produced and hosted by Casey Clapp and Al...

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 th...

The Baobab! One of Africa’s most storied and mythological trees, the baobab (Adansonia grandidieri) is one tall, thicc mother.

This week we head to Sierra Leone and take a look at their famous kapok, the Cotton Tree of Freetown ( Ceiba pentandra ). The kapok is a tree that has had uses for humans for thousands of years, but the Cotton Tree of Freetown was far more than just a useful tree representing the spirit of a nation.

We’re going on a Summer Vacation! First stop, Oaxaca, Mexico, to visit the sacred and legendary Árbol del Tule (Montezuma cypress, Taxodium mucronatum). This glorious and massive tree sits squarely in a church courtyard, and has found its way into the zeitgeist of Oaxacan culture. With a sordid taxonomic past, this tree tells a tall tale. But is it really a tree at all…? Completely Arbortrary is p...

What makes a tree popular? What keeps a tree popular? Ask the Colorado blue spruce (Picea pungens), whose commercial popularity has lasted decades with no sign of slowing down. The “Norm” to plant nurseries’ Cheers, this spruce is a common character from corporate courtyards to suburban yards. Plus, we ask the question: will this tree’s popularity ever end? Completely Arbortrary is produced and ho...

Our desert darling, the Blue Palo Verde ( Parkinsonia florida ) might just be one of the most desert-adapted trees in the west. Named after a funny pharmacist, this desert dweller is a team player as much as it is a lone wolf.

A tree of many names, the Alaska yellow-cedar ( Cupressus nootkatensis ) is a quintessential conifer with a plethora of identities. And in this episode, we discuss the wood of conifers, and how it differs from the wood of its harder, more broad-leafed counterpart.

If you like paniculatas, and getting caught in the golden rain, you’ll love this episode all about the golden rain tree (Koelreuteria paniculata).

In our final installment of Completely Arbortrary’s Excellent Adventure, we take it all the way back to the year 0, Kazakhstan, where we discuss the wolf to our apple’s dog, the Wolf apple (Malus sieversii). Today, we know apple as a supermarket produce section monopolizers, but these are simply the domesticated version of the wild animal that is sieversii, a Kazakhstani native from a different ti...

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...

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. Completely Arbortrary is produced and host...

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 fact...

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 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-lik...

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... Completely Arbortrar...

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. Completely Arbortrary is...
