Notes on Different Meanings

The two primary meanings refer to different botanical species: 1. Meaning 1 (Elymus repens): Focuses on its invasive method of spread via rhizomes. It is a perennial grass. 2. Meaning 2 (Panicum capillare): Focuses on its appearance, specifically its slender, brushy seed heads. It is an annual grass.

While both are weeds called "witch grass," they are identified by different characteristics: one by its below-ground growth and the other by its above-ground appearance.
