Barnyard Grass is an annual grass variety that usually begins its growth cycle germinating in Spring, and in some years may even begin germinating in Winter.

As a young plant, it will begin spreading along the ground with its leaves rolled into a bud-like shape and having a dark red tinge to its leaves, as the weed begins to mature its leaves will unfurl and begin pointing upwards into the familiar shape of wild grasses.

When mature, Barnyard Grass will reach an average height of around 5 feet, with an abundance of grassy leaves and sending out its flowering seed heads from June through to October.
