Boise is the capital of Idaho, located in the southwestern part of the state near the foothills of the Rocky Mountains. When one thinks about Idaho, it’s difficult to imagine the first thought being trees. After all, it’s a region better known for dry plains and sagebrush. Despite that image, the city of Boise stands out for a simple reason. It is unusually green. That contrast is why it has long been known as the “City of Trees,” a moniker that paints a very specific, lush image.
Where Boise’s City of Trees Nickname Comes From
The nickname goes back to Boise’s earliest history. In the nineteenth century, travelers crossing southern Idaho endured long stretches of arid terrain before reaching the Boise River Valley. Along the river, they encountered water and dense groves of cottonwood trees, a sharp and memorable change from the landscape they had just crossed.
That first impression mattered for settlers. Early accounts frequently described the area as lush and shaded compared to its surroundings. Over time, that reputation stuck, and the settlement became associated with its trees in a way few western cities were. It’s a nickname that also makes plenty of sense, as it gives Boise a very friendly, earthy image, one that persists to this day.
How Trees Became Part of Boise’s Identity
What makes Boise different is that it never lost that greenery as it grew. Instead of clearing trees to make way for development, the city planted more of them. Streets, parks, and residential neighborhoods were designed around trees, giving the city a real cozy vibe. Seeing as Idaho isn’t known for industry and towering skyscrapers, it makes sense that Boise didn’t shift away from the state’s natural, rustic identity.
Nature is at the heart of Boise, and the clearest example of this is the Boise River Greenbelt, a continuous corridor of trees and pathways that follows the river through the city. It connects downtown with surrounding neighborhoods and gives Boise a level of shade and walkability that surprises many first time visitors. Boise is a great place to live, especially if you want mid-tier city vibes with nature sprinkled throughout. It’s rare to see such a combo persist, especially in an era where new developments throughout the country threaten trees. Interestingly, Boise has over 85,000 trees and new ones are planted every year, which means trees will never go away. And compared to other nicknames that American cities have, like Cleveland being referred to as the “Mistake on the Lake,” we’re pretty sure Boise is happy with the title it has!
