The oak tree is a deciduous tree of the genus Quercus and has acorns and lobed leaves.It is the undisputed king of the western world.

In spring,they do bloom like all fruit-producing trees.New leaves begin to replace the old ones.In summer, the leaves undertake photosynthesis,and the rest of the tree uses the sugars it produces.When the fall comes,the leaves stop making chlorophyll and carotenoids and anthocyanins produce fall colors of red,orange and bronze.As winter comes,the leaves fall away and the tree remains dormant.
