One aspen grove in Utah, called Pando, is a single male clone with about 47,000 trunks on one root system, covering some 43 hectares and weighing around 6,000 tonnes. It is often called the heaviest known organism. Aspen leaves flutter in the faintest breeze on flattened stalks.

Populus tremuloides is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen. It is commonly called quaking aspen, trembling aspen, American aspen, mountain or golden aspen, trembling poplar, white poplar, and popple, as well as others. The trees have tall trunks, up to 25 metres tall, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in autumn. The species often propagates through its roots to form large clonal groves originating from a shared root system. These roots are not rhizomes, as new growth develops from adventitious buds on the parent root system. Wikipedia
