About This Plant

The bark of the Canadian Poplar (Populus x canadensis), often referred to as the Carolina Poplar, is generally smooth, light grey to greenish-grey in colour, and becomes furrowed with age. In young trees, the bark is relatively thin and smooth, while in mature trees, it develops deep furrows and ridges. Canadian Poplars are known for their rapid growth. They typically reach heights of 50 to 80 feet (15 to 24 meters), with a spread of around 30 to 50 feet (9 to 15 meters). Their tall, straight trunk and expansive crown make them a popular choice for landscaping and as windbreaks in various environments.

The Story


The leaves of the Canadian Poplar are generally broad, with a distinct deltoid or triangular shape. They feature a serrated margin, with fine teeth along the edges. The leaves typically have a smooth texture and a glossy, dark green colour on the upper surface. The underside of the leaves is often lighter in colour, ranging from light green to a whitish hue. The leaves are alternately arranged along the stems, and their size can vary, with an average length of about 7 to 15 centimetres. As a deciduous tree, the Canadian Poplar sheds its leaves in the autumn, displaying vibrant yellow hues before falling.


Populus canadensis produces distinctive fruit structures called capsules. These capsules contain numerous small seeds and are borne in hanging clusters. The capsules are roughly cylindrical, with a length of about 6 to 10 centimetres. They are green initially and turn brown as they mature. As the capsules mature, they split open, releasing cottony fibres that carry the seeds, aiding in wind dispersal.
