6. Eucalyptus Regnans
If you haven’t already figured out, most all of the biggest trees on the planet by volume have names given to them. Eucalyptus Regnan, an evergreen tree, goes by the name of “Still Sorrow”. However, it also has a slew of common names it tends to go by depending what region you are in. These names include, but are not limited to mountain ash, giant ash, and Victorian ash. I, myself, am more familiar with the terms mountain or giant ash. These are among some of the tallest of eucalyptus species on Earth, many reaching heights of over 300 feet tall! Still Sorrow happens to be the largest recorded mountain ash at 13,808 cubic feet by volume.
