Catkins appearing before leaves; catkin-scales laciniate, ovate to obovate. Male catkins 5–8 cm long; stamens 8–10, anthers reddish. Female catkins 5–10 cm long.

*EGL, *Gold, *HSF. Populus ×canescens is sometimes grown as a specimen or street tree in Victoria and is known to persist and spread via suckers in some localities.

A fertile hybrid derived from P. alba and P. tremula. Populus ×canescens is distinguished from P. alba by the irregularly erose-dentate to shallowly lobed long-shoot leaves that are thinly cobwebbed below, and catkin-scales that are laciniate. Whereas long-shoot leaves of P. alba are usually deeply palmatifid, with a densely hairy undersurface, and catkin-scales are entire.
