Winter annual grasses include:

Winter annual grasses include:

• A. Downy brome
• B. Cheat
• C. Jointed Goatgrass
• D. All of the above

Answer: (D)

Winter annual grasses are those that germinate in the fall, survive through winter, and complete their life cycle by producing seed in the spring. Downy brome is a classic example and is often called cheatgrass, Bromus tectorum, which germinates in fall, overwinters, and then bolts in spring to set seed. Jointed goatgrass follows the same fall-germinate, spring-seed pattern, making it another winter annual weed. Since cheatgrass and downy brome refer to the same species under different common names, and jointed goatgrass also fits this seasonal pattern, all of these fit the description. All of these are winter annual grasses.
