POPULUS TREMULA

Aspen – A large deciduous tree with a broad crown, sometimes suckering freely. Rounded leaves, bronze when young, tremble in a light breeze and turn yellow in autumn. Male trees have woolly grey catkins. Grow in moist but well-drained, humus-rich, fertile soils but avoid planting in vicinity of buildings due to vigorous root system; it has the potential to become a nuisance. Very useful as a screen or as part of a shelter belt and grows very rapidly.
