Lone Tree had only been founded a bit over a year ago in April 1997 when then mayor Jack O’Boyle planted the city’s signature tree: A blue Spruce at the corner of Lone Tree Parkway and Yosemite Street.

O’Boyle had been looking for a tree for which the city was named for a while – without success. It turned out, there was no such tree.

The early beginnings of Lone start in the 1980s as a residential development enveloping an Arnold Palmer-designed golf course. The previously undeveloped land had been recently graded for the development – with very few trees. Hence, the name of the city.

The placement of the signature tree seemed very logical: the original city boundaries ran from County Line Road south to Lincoln Avenue, and from Highlands Ranch east to Yosemite Street. Placing the tree at the corner of Lone Tree Parkway and Yosemite Street was like the perfect spot.

The mayor then finally purchased a 14-foot blue spruce from a nursery in Elisabeth. The tree was planted on Arbor Day in 1997.
