An Oak is a tree or shrub
in the genus Quercus, of which about 600 species exist on earth.
The flowers are catkins, produced in spring. The fruit is a nut called an acorn, borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on species.

HAIKU
fallen oak leaf ...
one by one my friends
reach half a century
. . . . .
In the square where we live, nine oak trees add presénce. It is a joy to watch them grow new leaves in spring and then to watch these leaves fall in autumn.
Right now, the branches are draped with snow.
