The Gatekeeper™ Aspen is a large, fast-growing tree with a columnar growth habit. Its large, heart-shaped green leaves turn a vibrant golden yellow in the fall. Known for its resistance to bronze leaf disease, the Gatekeeper™ Aspen is a hardy hybrid that thrives in most soil types and is tolerant of both drought and urban pollution. With its aggressive root system, it’s important not to plant this tree too close to foundations. The Gatekeeper™ is an excellent choice for shelterbelts, privacy screens, or as a striking vertical accent in any landscape.
