The enemy himself is the original tare.
Jesus explains this clearly in Matthew 13: 37-40.
He that soweth the good seed is the Son of Man. The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one;
The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.
As therefore the tares are gathered and burned in fire; so shall it be in the end of this world.
