Identifying Grass Seedlings

Witchgrass (Panicum capillare)

Summer annual grasses


Witchgrass is a tufted grass that may grow in a decumbent fashion, or upright, and reaches a height of about 30 inches. The sheaths and stems are round and densely covered with soft, stiff long hairs at a 90-degree angle to the stem and sheath. The blades are also covered with soft hair and are 4–12 mm wide. Auricles are absent, and the ligule is a frings of hairs. At maturity, the plant breaks off and is often referred to as “tumbleweed.”

Witchgrass is common throughout Missouri and much of the United States.
