About

Aspen is a deciduous, slender poplar tree of heathland, woodland and wet woodland, and can particularly be found in Scotland and Northern Ireland. Aspen is known as a 'colonial tree' because it spreads by growing suckers from its roots, from which new shoots appear; it can form extensive groves in this manner. However, Aspen also reproduces sexually through wind pollination: flowers can be seen from February to March, and the male and female catkins appear on separate trees.
