Populus alba leaves on vigorous shoots A. A. Reznicek leaves on vigorous shoots

A native of Europe, widely cultivated and spreading by suckers, sometimes forming small thickets along roadsides, at old homesites, in fields, and even into forests, especially in sandy soil. First collected in 1896 in St. Clair Co.

Staminate plants are apparently not in cultivation. A collection from Berrien Co. (F. A. Swink et al. 10187, MOR) is P. ×canescens (Aiton) J. E. Sm., a hybrid of P. alba × P. tremula, the European aspen. Like P. alba, this is apparently all pistillate in North America, so sterile and with only vegetative spread. It is similar to hybrids of P. alba × P. tremuloides (P. ×heimburgeri), which have been reported from Gladwin, Livingston, Midland, and Tuscola Cos., but has leaves more regular in their toothing and proportionately narrower. Populus alba × P. grandidentata (P. ×rouleauana) is reported from Jackson, Livingston, Saginaw, and Washtenaw Cos. It has much more coarsely and irregularly toothed leaves and more persistent white pubescence.
