説明（英語）: Genus of about 35 species of usually dioecious, mainly deciduous trees found in woodland, valley bottoms, riverbanks, and swampland in N. temperate regions. They are cultivated for their very rapid growth as specimen trees, and for their alternate, ovate, triangular-ovate or diamond-shaped leaves, often aromatic in bud and when unfolding. They have tiny flowers borne in catkins, generally 5-15cm (2-6in) long, mostly in late winter or spring, before the leaves. Male and female flowers are usually borne on separate trees, the females producing copious fluffy white seeds. Most poplars are useful as windbreaks; P. alba and P. x canescens will thrive in coastal sites. The vigorous root systems may damage drains and foundations, particularly on clay soil, so avoid growing poplars within 40m (130ft) of a building.

耐寒性（英語）: Fully hardy.
