Populus tremula, Aspen

Populus trmula or Apen is slender to slightly conical tree with rounded crown and tall, tapering trunk.

This row of Aspen is located on the Fallowfield Loop, forming a boundary between the Loop and playing ground on the other side. There is plenty of sunlight and the trees are growing vigorously and healthy. 

The soil conditions are damp.

The aspen grows up to 20m in height and its best known for its fluttering leaves, which rustle in the slightest breeze. Its bark is smooth and greyish green at first, becoming brown, ridged and fissured with age.

The leaves are rounder to slightly oval with shallow marginal teeth. They are green on both surfaces but paler below on long flattened petioles. In the autumn leaves may turn golden yellow especially further in the North. On South they fall quickly without a colour change.

Male trees produce reddish purple catkins up to 8cm long while the female trees  

have green tinged pink catkins.
