This Old Tree

A lone mulberry tree stands beside the Washington Monument. It is curious, unexpected, and impossible to ignore once you notice it. Who planted it? Is it historic? Is it one tree or two? Why is it preserved, when there is no other tree on the immediate grounds?

D.C. tree tour guide Sam Nelson chased down the answers, found in a 2014 government report. The author is landscape historian Jonathan Pliska, who also wrote A Garden for the President: A History of the White House Gardens. 

In celebration of America's 250th birthday, host Doug Still hands the mic to Sam and Jonathan for a conversation that explores the mysteries of this mulberry tree next to our iconic national monument. The story involves several early champions of 19th century horticulture, and the history of the National Mall itself.

Kongeegen, or the 1,500 year old “King’s Oak,” is deep inside a forest called Jægerspris Nordskov in Denmark. The tree is named after 19th century King Frederik VII, who owned a nearby castle with his wife, the Countess Danner. It is a national treasure and one of northern Europe’s oldest living oak trees.  

Getting there meant a two-mile hike through the woods with guests Anders Jensen of the Danish Tree Association and forest historian Helle Serup of The Green Museum. They tell the biological story of Kongeegen, and how Denmark sees its forests. 

But there is also a love story - a tangled affair between the unconventional Frederik, the Countess Danner (aka Louise Rasmussen), and a wealthy newspaper publisher named Carl Berling. The Countess's own love letters embellish this true story from her point of view - scandal, romance, and all  - and how it led them to seek shelter from the rain under this ancient oak.

Sa Melabrina is a Downy Oak tree the size of a small church, draped in moss and ferns. Her ancient arms spread wide in the surrounding forest near Illorai, Sardinia. She's the oldest and largest of her kind in all of Europe. And she's been standing here in these mountains for nine centuries.

What she symbolizes is even greater than her beauty.

The town’s mayor organized a remarkable conference drawing scientists, conservationists, and community leaders from across Sardinia and beyond, all united around a single idea: that Sardinia's ancient trees, its oldest living landmarks, could form a network worth protecting, visiting, and fighting for.

There is something else at stake. Sardinia's small towns are quietly shrinking. Depopulation is hollowing out villages that have survived for millennia. Saving these old trees is vital, but Sardinia's leaders ask a new type of question:

Can Sa Melabrina and Sardinia’s monumental trees save its small towns?

In the small Estonian town of Orissaare, football players dribble around a 150-year-old oak tree standing impossibly in the middle of their soccer field or "stadium." What seems like a quirky local oddity became a symbol of national pride when this tree won the 2015 European Tree of the Year, beating much larger countries like Hungary, Spain, and the UK.

How did an unknown Estonian oak outcompete all of Europe? The answer involves brilliant PR, ancient folklore, a fierce independence forged by centuries of foreign invasion, and a profound connection to forests rooted in animism. Could a tree resist the Soviets? Learn about its inspiring legend that captured the attention of tree-lovers around the world.

High up in California's Sierra Nevada mountains stands the largest tree on earth by volume - the General Sherman Tree. The famous giant sequoia has captivated millions of visitors, but few know the rich tapestry of stories woven around its massive trunk.

Join us as we explore the “Giant Forest” of Sequoia National Park with former park ranger and author William C. Tweed. From the indigenous Monache and Yokuts who first walked among these giants, to ambitious Euro-American explorers like John Muir, to a Black Army Captain who became the parks first true manager, discover how "first encounters" with giant sequoias become life altering events. 

What evolutionary secrets allow sequoias to get so big? Why do frequent fires help them to survive? And what is "sequoia time?" The General Sherman tree and its mates have changed how we view the natural world and our place within it.

Some trees are old — and then there's S’Ozzastru. Nestled near the village of Luras on the island of Sardinia, this ancient olive tree has stood for nearly 4,000 years. Also known as "The Great Patriarch" or "The Patriarch of Nature," the bronze age tree is a living witness to the rise and fall of civilizations.

How has it endured for millennia? Who, across the centuries, has found shelter beneath its branches? And will the millennial olive trees of Sardinia continue to survive?

Join us as we travel to the heart of the Mediterranean in search of secrets to one of the world’s oldest living trees. 🌿

Have you seen those breathtaking aerial photos of a solitary ginkgo tree in a courtyard, its leaves creating a perfect golden carpet of fallen leaves? This isn't just any tree—it's a 1,400-year-old living witness to history, standing tall within the walls of China's Gu Guanyin Buddhist Temple.

While its stunning autumn transformation goes viral online each year, the story behind this magnificent being remains largely unknown to Western audiences. Why was this particular tree planted at this particular temple? Could it really have been placed there by Emperor Taizong himself, one of China's most celebrated rulers? Why are ginkgo trees so special?

Join us as we unravel the mysteries of this famous ginkgo tree and explore its remarkable connection to the golden age of the Tang Dynasty.
