If patience was a plant, it would be a Bristlecone pine. Cautiously growing in the harsh terrain of Great Basin National Park in Nevada, these amazing trees can grow to be more than 5,000 years old. Gnarled, twisted and scattered in groves on rocky ground, Bristlecone pines make excellent subjects for photos, especially with a night sky or sunset backdrop.
