Fireweed, Aspens and Evergreen trees growing near and reflected in a pond in Northwest Colorado. At higher altitudes or in windy areas, trees can grow in convoluted ways, and these aspens were a perfect example of that. This is a summertime landscape, painted en plein aire.
Aspen is a common name for certain tree species; some, but not all, are classified by botanists in the section Populus, of the poplar genus.
The aspens are all native to cold regions with cool summers, in the north of the Northern Hemisphere, extending south at high altitudes in the mountains. They are all medium-sized deciduous trees reaching 15–30 m (49–98 ft) tall.
All of the aspens typically grow in large clonal colonies, derived from a single seedling, and spread by means of root suckers; new stems in the colony may appear at up to 30–40 m (98–130 ft) from the parent tree. Each individual tree can live for 40–150 years above ground, but the root system of the colony is long-lived. In some cases, this is f...
