About This Plant

The bark of Populus x canadensis ‘Robusta,’ commonly known as the Canadian Poplar or ‘Robusta’ Hybrid Poplar, is smooth and greyish-green in its youth, gradually developing into a rough, dark grey bark with furrowed ridges as the tree matures. The ‘Robusta’ Hybrid Poplar is known for its rapid growth. In optimal conditions, it can reach impressive heights, often exceeding 80 feet (24 meters) at maturity.

The Story

Leaf

The leaves of Populus x canadensis ‘Robusta,’ a variety of hybrid poplar, are large, deciduous, and broadly triangular in shape. These leaves exhibit a glossy, dark green colour on their upper surface and a slightly lighter shade on the underside. The margins are serrated with fine teeth, creating a distinctive and textured appearance. The leaves are arranged alternately along the stems and have a prominent midrib. ‘Robusta’ poplar leaves flutter in the breeze, showcasing their characteristic rustling sound. During the autumn season, the leaves may turn into a vibrant yellow before falling.

Produce

Populus x canadensis ‘Robusta,’ is a hybrid poplar tree that does not produce traditional fruits. Instead, it reproduces through its catkins, which are elongated, drooping clusters of small flowers. The male catkins release pollen, and the female catkins develop into capsules that contain numerous small seeds surrounded by cotton-like fibres. These capsules resemble cotton and are released in the wind to disperse the seeds.
