Some of the most beautiful fall colours happen when the trees and shrubs in a grouping all turn colour at once. That's the case with Sumacs and Poplars. Sumacs grow as a clonal colony through suckers. So you will see a hillside of startling orange-red.
Quaking aspen also are clonal colonies. The Poplar named Pando has been tracked as a colony in the Fremont River Ranger District on the Colorado Plateau in south-central Utah. It is 108 acres. It has been estimated to weigh 6,000 tonnes so would be the heaviest known organism. While individual trees live around 100 years, the whole organism is estimated to be up to 14,000 years old. How many stems are there? 40,000 trunks/stems.
