The Tower Poplar (AKA Lombardy Poplar) is the largest columnar tree commonly available in Alberta. Though still only spreading out 4-6′ at chest height; it offers a way to enjoy the grandeur and awe of a formidable, large tree, while only occupying a narrow section of the yard.

What you Need To Know:

  • Lifespan: With proper care, Tower Poplars can live for 60-100 years, offering a long-lasting vertical presence in your landscape.
  • Canopy Size and Spread: Maintains a narrow spread of only 10-15 feet at maturity, perfect for small spaces.
  • Growth Rate: Extremely fast grower, adding up to 5-8 feet per year under ideal conditions.
  • Canopy Height: Reaches a mature height of 40-60 feet, creating a tall, slender presence.
  • Soil Preference: Adapts to various well-drained soils and even tolerates some clay or alkaline conditions.
  • Water Needs: Moderately water-dependent, especially during the first few years after planting and during dry spells. They become more drought-tolerant with age.
  • Light Preference: Full sun exposure is ideal for optimal growth.
  • Hardiness Zone: Hardy in USDA zones 3-9, tolerating a wide range of temperatures.
  • Flowers: Inconspicuous catkins appear in spring before the leaves emerge, but they are not particularly showy.

Interesting Facts

  • Shallow and Spreading Roots: Tower Poplars have aggressive root systems that can disrupt sidewalks, foundations, or underground utilities. Plant them a significant distance away from any structures.
  • Susceptibility to Diseases and Pests: These trees can be prone to canker diseases, borers, and other pests, especially as they age.
  • Rapid Growth: The Tower Poplar is one of the fastest-growing trees available. It’s often used for creating a quick privacy screen or windbreak.
