The banyan tree is an interesting tree with many roots growing down from its branches.
It can be found in south China and other parts of Asia.
When its roots reach the ground, they plant themselves and grow bark.
Eventually they either become part of the original tree trunk or become separate tree trunks.
Using this method, banyan trees can cover an enormous area.
The world's largest banyan tree, in India, covers an area larger than a football pitch.
Even though it is only one tree, it looks like a whole forest!
Speaking of trees, a gingko tree believed to be around 2,800 years old was recently discovered in Hebei Province, China.
Many gingko trees have been around for more than 1,000 years -- that is the reason why they are known as 'longevity trees' in China.
While gingko trees can live for a long time, they are not even near being the oldest trees.
Bristlecone pine trees in America are among the oldest living trees.
One bristlecone pine tree in Nevada is over 4,600 years old!
