Populus tremuloides is one of North America's most widely distributed tree species, here growing on a stable scree slope at around 1700 m asl in Oregon's Wallowa Mountains (15 June 2022).

A large, heavily branched tree, retaining its foliage until late in the autumn. It attains a large size in the warmer parts of Europe, but is rare in this country and not entirely hardy.

A tree 100 ft high in the wild, but rarely more than half as high in this country, producing suckers freely; young shoots smooth, round; winter-buds thickly covered with a balsamic, very fragrant, viscid, yellowish resin, often 1 in. long, long-pointed.

The UK champion Populus nigra 'Italica' is this 38.5 m tree near Drumnadrochit in the Scottish Highlands. It belongs to a variant with sometimes pubescent young growths which is better able to thrive in the cool summers of the far north-west of Europe.

A straight-stemmed clone of Populus balsamifera subsp. trichocarpa (syn. P. trichocarpa), probably 'Fritzi Pauley', at the Brechfa Forest Garden, Carmarthenshire, UK; fast-growing young trees to 31 m tall in May 2018.

Populus tremula 'Erecta' has been widely planted in tight urban spaces, such as here between tram lines and a busy road on the waterfront in Gothenburg, Sweden.

2007年6月30日 · This is a very vigorous and handsome poplar, which produces suckers freely, and grows well on most soils, including chalky ones. It is used for shelter and, in some parts of the world, for checking soil-erosion.

In regard to its foliage this is the most remarkable and striking of all cultivated poplars. I gathered a leaf on a small tree in the Coombe Wood nursery in October 1908, 14 in. long by 9 in. wide (without the stalk). The leaves do not decrease much in size as the tree grows older.

It is a female clone the history of which is unknown, but most probably it arose in north-eastern N. America, where it has been cultivated since early colonial times as a shade tree, and was introduced from there to Europe in the 18th century.

A tree up to 80 ft high in cultivation; young stems angled and hairy at first, becoming terete and glabrous, brownish green the first season, greyish the second; lateral buds slightly viscid, slender, loosely appressed.
