The fruit that the tree produces is the acorn. An oak tree does not start producing acorns until it is between 20 – 50 years old! An oak tree can produce a staggering 2,000 acorns a year with only 1 in every 10,000 growing into another oak tree.

The trees make both female and male flowers, the female being much smaller than the male. Male flowers are known as catkins and can be found growing in clusters.
