The aspen

A sizeable aspen grows on the roadside, on the edge of a small wood of fellow-aspens. This tree has a smooth, greenish trunk and rounded, crenelated leaves which take on magnificent colours in autumn. The stem, or petiole, of aspen leaves is flat and twisted, so it can be caught by the slightest breeze making the foliage «quake» hence its common name, the quaking aspen. It grows in places where the soil is quite damp.
