OPQ Aspens
Aspen is the name of six very similar
poplar species common all over the temperate and subarctic regions of
the northern hemisphere. The most widespread are the European/Asian
populus tremula and the American populus tremuloides.
The typical aspen has a slender, long
trunk with a bark ranging from almost white to dark gray, always with
a slight greenish tint. The further north, the darker the bark tends
to be. Older trunks have fissured bark but aspen trunks don't often
grow very old. The root system system of the plant can last for a
long time though, one American aspen is believed to be a staggering
80,000 years old(!) A single plant usually has multiple trunks, in
clusters and spread across a wider area, making a grove or small
forest.
