Landscape Attributes
Robusta Poplar is a deciduous tree with a shapely oval form. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.

Robusta Poplar is recommended for the following landscape applications;
- Shade
- Windbreaks and Shelterbelts
Planting & Growing
Robusta Poplar will grow to be about 60 feet tall at maturity, with a spread of 40 feet. It has a high canopy with a typical clearance of 7 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for 60 years or more.
This tree should only be grown in full sunlight. It is an amazingly adaptable plant, tolerating both dry conditions and even some standing water. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selection of a native North American species.
