Grey Poplar - Populus alba x tremula = P. x canescens

Alternative names
Populus x canescens
Description

A natural hybrid between White Poplar and Aspen, and rather variable but intermediate in character between the two.  It exhibits 'hybrid vigour', and can outgrow both parent species, becoming a large tree to 40 metres or more. 

Shoots white downy at first. Leaves rounded-triangular, coarsely and irregularly toothed, not lobed, dark green above, grey downy beneath.  Bracts are laciniate.  As with all poplars, the leaves from suckers and epicormic growth are often atypical and should not be used to identify the species. 

Most trees are male, and the male catkins are greyish becoming red-purple as they mature. Female trees are rare, and have greenish catkins.
