Qual è l'albero più antico di Boise?

The sequoia's age comes from its original planting date at the Pittenger family home around 1912, recorded in the Idaho Big Tree Program's champion register at its old address before a hospital expansion forced the 2017 move. Family history says the seedling arrived from California by way of the naturalist John Muir, a story repeated for a century and resting on the family's own telling rather than any document, kept here as the story the tree arrived with rather than a fact. Moving a hundred-year-old sequoia was a gamble; the arborists on the job put its remaining span at three to five more centuries if the roots took hold, and nine years on it is thriving in a public park. Two other champions in Julia Davis Park, a bur oak and a Kentucky coffeetree, are each the largest of their species recorded in Idaho, but the state's register measures size rather than years and gives no age for either. The fourth tree, a young horse chestnut grafted from the Amsterdam tree Anne Frank watched from the annex window, is only about a decade old, the newest planting on this list by far, at the city's own Anne Frank memorial downtown.
