Mountain Sentinel® is a striking columnar variety of Quaking Aspen prized for its extremely upright, narrow form and elegant vertical presence. Its dense, upright branching makes it ideal for privacy screens, windbreaks, and urban landscapes where space is limited. The rounded green leaves tremble in the slightest breeze, creating soft movement and gentle sound. In autumn, the foliage turns a brilliant golden yellow, providing vibrant seasonal color. Fast-growing and exceptionally cold-hardy, this tree performs well in northern and mountainous climates.
Mature Height: 40–50 feet (12–15 meters)
Spacing: 6–10 feet (1.8–3 meters) apart
Features a columnar growth habit, perfect for narrow spaces, vertical accents, and formal plantings.
Exhibits the signature “quaking” leaves of Populus tremuloides, adding motion and texture to the landscape.
Less likely to spread aggressively than standard Quaking Aspen, maintaining a tidy, upright profile.
Fast-growing and highly cold-hardy, suitable for northern and mountainous regions.
Provides excellent seasonal interest with bright yellow fall foliage.
WH (Whip) trees establish quickly and adapt well after transplanting.
Grow Zone: 2–6
