GUARDIAN COLUMNAR ASPEN Populus tremuloides ‘Guardian’
• A fast‑growing, extremely narrow selection of native trembling aspen, valued for its tight columnar habit that fits beautifully into small yards, shelterbelts, and urban plantings.
• Features the classic trembling aspen foliage—round, glossy green leaves that flutter and shimmer with the slightest breeze, adding movement and sound to the landscape.
• Smooth, pale bark provides striking winter contrast and year‑round ornamental appeal.
• Produces small, early‑spring catkins that are light, dry, and short‑lived; they provide pollen for early pollinators and are not considered messy.
• Exceptionally hardy and adaptable to prairie soils, including clay and alkaline conditions; strong tolerance to wind, cold, and drought once established.
• Full Sun
• Zone 2, 12–15 m Height × 3–4 m Width
