Pinus aristata, commonly known as Bristlecone Pine, is a slow-growing conifer famed for its extreme longevity and resilience, often thriving in poor soils and high elevations. Its distinctively twisted needles, which are blue-green and dotted with resin glands, make this tree especially unique and appealing for rock gardens or xeriscape designs. It produces small cones marked by bristle-like appendages, inspiring its name. Bristlecone Pines are excellent for rugged landscapes or specimen use where their ancient, sculptural appearance can stand out.
