the prettiest tree

there is a tree
the prettiest tree
you can see if you look hard
and it grows in my yard;
it dresses in white
in the spring
therefore I think
it must certainly be
a lady tree;
but wait I am not sure
cause most of the times
it dresses in green;
the liveliest green
you have ever seen;
later when it is time for fall
it darkens to brown
and here and there
a patch of red
I see in her hair.
the strangest habit it has
when I dress in sweaters
my tree is bare
to the branches and bones;
so the squirrels must run
up and down the tree trunk
as hard as they can
to keep my pretty tree warm.
