Zombie vs Plants

And the green is good.
Sunflower shining where the streetlight died,
A row of little soldiers standing by my side.
They shuffle and they moan and they claw at the gate,
But a man with a garden don't answer to fate.
So I dig and I plant and I bury my fear,
Grow a little heaven while the horde draws near.
So root me down, let them come and awake.
