Columnar Populus tremula ‘Erecta’

Hardiness Zone: 2-5
Height: 40 feet
Spread: 10 feet
Sun: full
Soil Composition: rich and consistently moist, well-drained soil, clay tolerant
Water Needs: moderate, tolerates dry and flooded soil Growth Rate: moderate

Description: This tree should suit Laramie’s winters as it was developed for cold, northern regions. Introduced to the nursery trade in 1911 in Sweden, but grown there since the 1800s. It works best in groves, making it a great windbreak and privacy screening, but still does well near streets as they are road salt tolerant. Thanks to their narrow form, they will fill tight spaces in your landscape.
Ornamental Features: Similar to the native aspen, the flat, rounded green leaves flutter and rustle in the breeze, providing a soothing sound and visual appeal. Bright orange and yellow fall foliage. Inconspicuous flowers grow in April-May. Beautiful light gray, smooth bark that on newer growth is darker grey to black.
Planting & Growing: Best planted on north or east-facing sites but avoid hot and dry exposures. During first growing season, water deeply to help establish a sustaining root system. Before new growth starts in the spring, feed with a general purpose fertilizer.
Best grown in front/back yards, and in the landscape parking strip at LEAST 7 feet wide, along city streets. Plant at least 10 feet from fire hydrants, ground mounted utility boxes, buildings, fence, and driveways. Plant at least 10 feet from shrubs and other similar-sized trees. Plant 15 feet from large trees.
