The Oldest and Largest Living Trees
1. Bristlecone Pine
The bristlecone pine is now thought to be the oldest living tree. Two names are used
for this plant. Pinus aristata is used for a western pine that has some of the oldest
trees in the white mountains of California. The needles are in clusters or 5 and the
small cones have bristles. Pinus longaeva is sometimes used just to refer to the
specific plants in the white mountains. The common name ancient pine is used.
Bristlecone pine has been dated to over 4900 years old. These trees are not the
typical evergreen tree, but large trunks with green branches here and there, and not
all solid growth. They are very picturesque plants.
2. Redwoods
The redwoods or sequoia’s are the next oldest living trees. Sequoia sempervirens
is one of the largest (over 360 ft. tall) and oldest trees, some dated to over 2200 years
old.
3. Other Large trees
The kauri pine (Agathis australis) in New Zealand, and the Eucalyptus in western
Australia also grow to considerable size.
