The aspen

Near the ruined mill, you can see a stand of tall trees with smooth, greenish trunks 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 needs dampish soils and plenty of light and so it grows in clearings.
