Populus ×canadensis Moench

Grey Poplar

A hybrid P. deltoides × P. nigra. Large tree with greyish to white bark becoming fissured. Young shoots grey to yellowish, cylindrical to slightly angled. Buds sticky. Leaves broadly ovate to triangular, sometimes without glands at junction with the flattened leaf stalk, margins sometimes slightly hairy at first. Catkins 3-6 cm long. [P. ×euramericana (Dode) Guinier ]

Garden Origin

The fast-growing 'Euro-american' hybrids between the American P. deltoides and European P. nigra (easily propagated by cuttings) have been produced many times both spontaneously and artificially, and a range of clones selected. They are probably the most widely grown poplars in the United Kingdom. However, these have not been fully assessed and determined in Australia because of a long historical confusion with P. deltoides and the difficulties in distinguishing clones.

Differs from P. deltoides in having shorter catkins, occasional absence of glands at the leaf bases and fine hairs generally absent from the leaf edges.

Populus ×canadensis 'Aurea'

Trees male, producing catkins at the end of October. Massive, widely planted and easily recognised by the yellowish crowns that are pale lime-green in spring but become more yellow through the summer. The leaves have a translucent, sparsely ciliate edge often without glands at the junction of leaf blades and stalks (which are sometimes reddish). [P. monilifera 'Aurea', 'Serotina Aurea']

P. 'Serotina Aurea' is similar.

A bud mutation originating in the Van Geert Nursery, Ghent, Belgium in 1867.

Populus ×canadensis 'Veronese'

Young foliage reddish brown in spring. Suitable for a range of conditions and soil types. A good specimen tree or wind break with non-suckering roots but susceptible to rust fungus. Imported to Australia from Palmerston North, New Zealand, the original stock coming from the Institute of Poplar Culture at Casale, Monferrato, Italy.
