Quackgrass (Elytrigia repens) does not produce green seeds. The flowers of the quackgrass plant are green and resemble heads of wheat. The seeds form after the green flowers in September and are tan-colored with long, tapered tips. The seeds dropped in fall germinate in the early spring of the following year.
