Pine trees! Namely the blue spruce, Utah's state tree.
In 1933, this magnificent tree was chose as our state tree by Utah State Legislature. This tree grows wild in the Wasatch and Uinta Mountains (they love 6,000 to 9,000 feet elevation climates) and can be transplanted successfully into your yard in these surrounding areas.
The needles are silvery blue. They can grow as tall as 18 to 21 meters high tall!
Utah has a national champion in Ashley National Forest. It is 186 inches in circumference, 122 feet tall, and the crown spread of 36 feet!
