Witchgrass
(Panicum capillare)

Overview

---

The species Panicum capillare is a summer annual grassy weed that reproduces by seed. Witchgrass is primarily a weed of agronomic importance in crops, gardens, and landscapes and can be found throughout North America. However, this species of plant is extremely valuable for foraging mammals and birds, as its leaves and seeds are important food sources for many animal species.  At maturity, Witchgrass seed heads roll and tumble propelled by the wind, dropping seeds.

Main description

Seedling
The seedling of Witchgrass has hairy leaf blades, sheaths and lacks auricles (little hooks surrounding the leaf blade), which makes its identification easier among other grassy weeds.

Mature plant
The mature P. capillare has leaves covered in hair on both the upper and lower surfaces. The leaves have an inconspicuous middle vein. The stems grow erect, reaching nearly 90 cm, and are covered in short hairs. The flowers of Witchgrass bloom from June to September and result in an erect flower head.
