Populus × canadensis, known as Canadian poplar or Carolina poplar, is a naturally occurring hybrid of Populus nigra and Populus deltoides. It is a vigorous, broadly columnar, deciduous tree growing to 40 m (130 ft), which is commonly used by landscape architects. Cultivars include 'Robusta' and 'Aurea' (golden poplar  or golden Carolina poplar), which has won the Royal Horticultural Society's Award of Garden Merit.
A variable tree that occurred as a spontaneous cross between P. nigra and P. deltoides. The crown is usually broad oval to practically round, but sometimes narrower depending on the cultivar. The grey trunk has shallow grooves. The moderately glossy leaves are triangular and have a heart-shaped to straight foot, depending on the cultivar. The leaves are also green when they emerge and they can turn yellow in the autumn. Prefers moist, open, nutritious soil. It does not stand up well to stagnant groundwater or fluctuating groundwater levels. In general its resistance to canker and leaf spot disease is good to exceptional. But it is reasonably sensitive to rust. Various of these hybrid-derived cultivars can find good use in wide streets and avenues, planted in rows and in urban and landscape settings. Can be used in coastal areas thanks to its sturdy resistance to (sea) wind. An important producer of wood for clogs, pallets etc.
